feat(extension): add --background option to keep the browser in the background - #43864

…ackground With --background, the extension does not activate the connected tab or focus its window, client tabs open in the background, and bringToFront does nothing. With a token, Chrome opens the connect page with --open-in-background. Fixes: microsoft#42973

🟢 The CI failure matches a pre-existing flakeHi, I'm the Playwright bot. I checked the latest MCP report and the test's CI history. The reported failure is not likely caused by this PR. DetailsPre-existing flake
The refreshed CI database shows the same test, project, and Ubuntu Chromium bot failed in 10 of 736 run attempts outside this PR and passed in the other 726. The identical after-reload error occurred on main at This PR adds opt-in background behavior to extension connections.

## ✨ Highlights - **🌙 Keep the browser in the background** ([microsoft/playwright#42973](microsoft/playwright#42973)) — connecting through the extension activated the tab and focused the browser window, taking the screen from the app you were working in. Pass `--background` alongside `--extension` (config `background: true`, env `PLAYWRIGHT_MCP_BACKGROUND=1`) to leave the connected tab inactive and its window unfocused, and to open the client's new tabs in the background. With `PLAYWRIGHT_MCP_EXTENSION_TOKEN` set, the connect page opens in the background too (Chrome 158.0.8127.2 or later, with the browser already running). Requires extension 0.5.0 or later. Chrome throttles timers and animation frames in background tabs. ([microsoft/playwright#43864](microsoft/playwright#43864)) - **🗂️ Leave tabs out of the Playwright tab group** ([microsoft/playwright#43038](microsoft/playwright#43038)) — the extension always moved the tabs a client controls into its own tab group. Pass `--no-tab-group` alongside `--extension` (config `tabGroup: false`, env `PLAYWRIGHT_MCP_NO_TAB_GROUP=1`) to keep the selected tab and the tabs the client opens in their existing groups, if any. Connection approval is unchanged, each controlled tab still belongs to one client, and the extension's status page lists the controlled tabs. Requires extension 0.5.0 or later. ([microsoft/playwright#43814](microsoft/playwright#43814)) - **👁️ Match only visible elements** ([microsoft/playwright#43855](microsoft/playwright#43855)) — a locator could resolve to a hidden element, or fail because a hidden duplicate matched as well. Set `browser.contextOptions.locateOnlyVisible: true` in the config file to restrict locators to visible elements, both in the `target` of element tools such as `browser_click` and in `browser_run_code_unsafe`, as if `.filter({ visible: true })` ended each of them. A locator that ends with its own visibility filter keeps it. Off by default. ([microsoft/playwright#43903](microsoft/playwright#43903)) - **🏷️ Keep container names in snapshots** ([microsoft/playwright#43809](microsoft/playwright#43809)) — dialogs, landmarks and tables could appear unnamed even when their heading or caption was visible. `browser_snapshot` now retains identifying names on containers and table headers when the text supplying the name also appears among their children. ([microsoft/playwright#43810](microsoft/playwright#43810)) - **🎯 Find custom form controls by label** ([microsoft/playwright#43898](microsoft/playwright#43898)) — native `<label>` associations were ignored for form-associated custom elements. Element tools now recognize these controls through targets such as `getByLabel('City')`, and accessible names use the associated labels too. Both `for` attributes and nested labels are supported. ([microsoft/playwright#43900](microsoft/playwright#43900)) ## 🐛 Fixes - `fix(aria): restore snapshot visibility rules for inert and modal content` — the filtering announced in v0.0.84 is reverted: `browser_snapshot` no longer hides content solely because it is inert or outside a modal dialog. Click, fill and select actions still wait for explicitly inert targets to become non-inert ([microsoft/playwright#43792](microsoft/playwright#43792)). ([microsoft/playwright#43850](microsoft/playwright#43850), [microsoft/playwright#43851](microsoft/playwright#43851)) - `fix(mcp): preserve non-JSON evaluation results` — `browser_evaluate` returns readable representations of values such as BigInt, `NaN`, `Infinity`, `undefined` and circular objects instead of losing values or failing JSON serialization. JSON-compatible results keep their existing format ([#1838](#1838)). ([microsoft/playwright#43973](microsoft/playwright#43973)) - `fix(mcp): resolve config file paths relative to their source` — profile, executable, storage-state, output and other file paths in a config resolve against that file's directory, or its target's directory for a symlink. CLI and environment paths remain relative to the working directory. Extension connections also honor the merged executable-path configuration ([#1836](#1836)). ([microsoft/playwright#43970](microsoft/playwright#43970)) - `fix(extension): report lost tab instead of crashing` — tool responses report when a page closes before its snapshot can be captured. Extension connections also explain that Chrome may have detached the debugger because of an unsupported frame, rather than crashing response rendering ([microsoft/playwright#43230](microsoft/playwright#43230)). ([microsoft/playwright#43863](microsoft/playwright#43863)) - `fix(mcp): bound settle waits when page timers cannot run` — tool calls no longer hang during their settling delay when page timers are throttled, paused or otherwise unable to run ([microsoft/playwright#43752](microsoft/playwright#43752)). ([microsoft/playwright#43767](microsoft/playwright#43767)) - `fix(mcp): report event listener exceptions as console errors` — exceptions from page and context listeners installed through `browser_run_code_unsafe` appear in tool responses and `browser_console_messages` instead of escaping as unhandled errors ([microsoft/playwright#43770](microsoft/playwright#43770)). ([microsoft/playwright#43686](microsoft/playwright#43686)) - `fix(mcp): validate device names and preserve device descriptors` — unknown `--device` values produce an explicit error, and per-client overrides no longer mutate shared device presets ([#1834](#1834)). ([microsoft/playwright#43971](microsoft/playwright#43971)) - `fix(mcp): report one-based console source lines` — source locations in `browser_console_messages` and console entries in tool responses now use editor-style line numbers starting at 1 ([#1839](#1839)). ([microsoft/playwright#43975](microsoft/playwright#43975)) - `fix(mcp): clarify screenshot actions with vision tools` — the `browser_take_screenshot` description no longer rules out acting on a screenshot. `browser_snapshot` stays the default for actions; with `--caps=vision`, the description points to the coordinate-based mouse tools for elements that the snapshot does not expose, such as canvas content ([#1816](#1816)). ([microsoft/playwright#43857](microsoft/playwright#43857)) - `fix(aria): match mixed-case selected options in accessible names` — snapshots and role locators include the selected option's text when a custom listbox uses a mixed-case value such as `aria-selected="TRUE"` ([microsoft/playwright#43785](microsoft/playwright#43785)). ([microsoft/playwright#43787](microsoft/playwright#43787)) - `fix(chromium): preserve fonts when connecting with noDefaults` — extension connections no longer overwrite the existing browser's font settings, avoiding unexpected changes to page rendering ([microsoft/playwright#43715](microsoft/playwright#43715)). ([microsoft/playwright#43773](microsoft/playwright#43773)) - `fix(chromium): honor Linux config directories for channel connections` — extension profile lookup respects `CHROME_USER_DATA_DIR`, `CHROME_CONFIG_HOME` and `XDG_CONFIG_HOME`. Channel-based `--cdp-endpoint` connections also use the WebSocket path advertised in `DevToolsActivePort` ([microsoft/playwright#43880](microsoft/playwright#43880)). ([microsoft/playwright#43884](microsoft/playwright#43884)) - `fix(chromium): preserve HTTP navigations across HTTPS upgrade modes` — in browsers launched by the server, `browser_navigate` keeps HTTP URLs on HTTP instead of Chrome automatically upgrading them to HTTPS ([microsoft/playwright#43871](microsoft/playwright#43871)). ([microsoft/playwright#43877](microsoft/playwright#43877)) - `fix(chromium): account for tabs and toolbar in the new headless mode` — with `--headless`, Chrome and Edge now size their window to fit the viewport below the tab strip and toolbar, so videos from `browser_start_video` (opt-in via `--caps=devtools`) no longer lose the bottom of the page. ([microsoft/playwright#43904](microsoft/playwright#43904)) - `fix(screenshot): support full-page SVG documents` — `browser_take_screenshot` with `fullPage: true` works on standalone SVG documents instead of waiting for a nonexistent HTML body ([microsoft/playwright#43962](microsoft/playwright#43962)). ([microsoft/playwright#43972](microsoft/playwright#43972)) ## 📦 Upgrading Configs that use `@playwright/mcp@latest` pick this release up on the next client restart.

## ✨ Highlights - **🪟 Let agents use your logged-in browser without taking over your screen** ([microsoft/playwright#42973](microsoft/playwright#42973)) — `PLAYWRIGHT_MCP_BACKGROUND=1 playwright-cli attach --extension=chrome` keeps controlled tabs and the browser window in the background. You can also set `"background": true` in your CLI config. ([microsoft/playwright#43864](microsoft/playwright#43864)) - **🎬 Record the whole viewport in headless Chrome and Edge** — `playwright-cli video-start` no longer loses the bottom of the page to browser-toolbar sizing in the new headless mode. Trace screenshots benefit too. ([microsoft/playwright#43904](microsoft/playwright#43904)) - **🧭 Snapshots keep the names agents need** ([microsoft/playwright#43809](microsoft/playwright#43809)) — `playwright-cli snapshot` preserves identifying names on dialogs, landmarks, tables and column headers, even when their heading or caption also appears below them. ([microsoft/playwright#43810](microsoft/playwright#43810)) - **👁️ Ignore hidden duplicate elements by default** ([microsoft/playwright#43855](microsoft/playwright#43855)) — set `"browser": { "contextOptions": { "locateOnlyVisible": true } }` in your CLI config, then run `playwright-cli open --config=cli.config.json`. Locators resolve only visible matches, avoiding strict-mode failures from hidden, cached UI. This is opt-in. ([microsoft/playwright#43903](microsoft/playwright#43903)) - **🗂️ Keep your tab strip free of agent-created groups** ([microsoft/playwright#43038](microsoft/playwright#43038)) — set `"tabGroup": false` in your CLI config and use `playwright-cli attach --extension=chrome --config=cli.config.json`. Extension sessions can control tabs without creating a Chrome tab group or changing your existing groups. ([microsoft/playwright#43814](microsoft/playwright#43814)) ## 🐛 Fixes - `fix(cli): use ordinal filenames for repeated downloads` — repeated downloads of `report.csv` become `report-1.csv`, `report-2.csv`, and so on instead of silently overwriting earlier files. ([#514](#514), [microsoft/playwright#44011](microsoft/playwright#44011)) - `fix(cli): restrict profile deletion to the exact session` — `playwright-cli -s=work delete-data` no longer deletes the persistent profile of `work-test`. ([#499](#499), [microsoft/playwright#43928](microsoft/playwright#43928)) - `fix(cli): report command failures in text and JSON modes` — invalid arguments and startup failures produce a readable error, or an `{ "isError": true, "error": "..." }` object with `--json`, and exit with code 1 instead of exposing an unhandled rejection. ([#502](#502), [#522](#522)) - `fix(cli): use CLI command names in error messages` — validation errors and recovery hints name commands you can actually run, such as `requests` and `recording-start`, rather than MCP tools, and avoid doubled `Error:` prefixes. ([#515](#515), [microsoft/playwright#43932](microsoft/playwright#43932)) - `fix(cli): avoid killing Windows process enumerators` — `playwright-cli kill-all` correctly reports the daemons it stopped on Windows instead of saying none were found. ([#525](#525), [microsoft/playwright#44008](microsoft/playwright#44008)) - `fix(mcp): preserve non-JSON evaluation results` — `playwright-cli eval '() => 10n'`, circular objects, regular expressions and special numeric values are represented without turning successful evaluations into serialization errors or losing their values. JSON-compatible results retain their existing format. ([microsoft/playwright-mcp#1838](microsoft/playwright-mcp#1838), [microsoft/playwright#43973](microsoft/playwright#43973)) - `fix(mcp): resolve config file paths relative to their source` — relative profile, storage-state, executable and output paths now resolve next to the config file, including `.playwright/cli.config.json` and `~/.playwright/cli.config.json`, rather than the working directory. Paths supplied through flags or environment variables remain relative to the working directory. ([microsoft/playwright-mcp#1836](microsoft/playwright-mcp#1836), [microsoft/playwright#43970](microsoft/playwright#43970)) - `fix(mcp): validate device names and preserve device descriptors` — an unknown `--device` reports a clear error instead of silently disabling emulation; context overrides no longer mutate shared device presets. ([microsoft/playwright-mcp#1834](microsoft/playwright-mcp#1834), [microsoft/playwright#43971](microsoft/playwright#43971)) - `fix(mcp): bound settle waits when page timers cannot run` — commands such as `eval` and `click` no longer hang during their post-action wait on CSP-sandboxed pages or pages with paused clocks. ([microsoft/playwright#43752](microsoft/playwright#43752), [microsoft/playwright#43767](microsoft/playwright#43767)) - `fix(mcp): report event listener exceptions as console errors` — exceptions in page or context listeners registered with `run-code` appear in console output instead of terminating the session. ([microsoft/playwright#43770](microsoft/playwright#43770), [microsoft/playwright#43686](microsoft/playwright#43686)) - `fix(mcp): report one-based console source lines` — `playwright-cli console` reports line numbers that match editors and DevTools. ([microsoft/playwright-mcp#1839](microsoft/playwright-mcp#1839), [microsoft/playwright#43975](microsoft/playwright#43975)) - `fix(extension): report lost tab instead of crashing` — losing the last controlled tab produces an actionable error instead of an undefined-property exception, with guidance when another extension's frame may have caused debugger detachment. ([microsoft/playwright#43230](microsoft/playwright#43230), [microsoft/playwright#43863](microsoft/playwright#43863)) - `fix(chromium): honor Linux config directories for channel connections` — browser discovery and attachment respect `CHROME_CONFIG_HOME` and `XDG_CONFIG_HOME`; CDP connections also use the WebSocket path recorded by Chrome instead of failing with a 404. ([microsoft/playwright#43880](microsoft/playwright#43880), [microsoft/playwright#43884](microsoft/playwright#43884)) - `fix(chromium): preserve fonts when connecting with noDefaults` — attaching to an existing headless browser preserves its font settings and page layout. ([microsoft/playwright#43715](microsoft/playwright#43715), [microsoft/playwright#43773](microsoft/playwright#43773)) - `fix(chromium): preserve HTTP navigations across HTTPS upgrade modes` — explicit HTTP URLs and HTTP route mocks stay on HTTP instead of being unexpectedly upgraded or failing in Chromium, Chrome and Edge. ([microsoft/playwright#43871](microsoft/playwright#43871), [microsoft/playwright#43877](microsoft/playwright#43877)) - `fix(screenshot): support full-page SVG documents` — `playwright-cli screenshot --full-page` captures standalone SVG documents instead of timing out. ([microsoft/playwright#43962](microsoft/playwright#43962), [microsoft/playwright#43972](microsoft/playwright#43972)) - `feat(actionability): wait for elements to be non-inert` — clicks, fills and option selection wait for inert subtrees to become interactive. Inert elements and content outside modal dialogs remain available in snapshots and role locators. ([microsoft/playwright#43792](microsoft/playwright#43792), [microsoft/playwright#43850](microsoft/playwright#43850), [microsoft/playwright#43851](microsoft/playwright#43851)) - `fix(selectors): support labels for form-associated custom elements` — label locators and accessible names recognize labels associated with custom form controls. ([microsoft/playwright#43898](microsoft/playwright#43898), [microsoft/playwright#43900](microsoft/playwright#43900)) - `fix(aria): match mixed-case selected options in accessible names` — embedded comboboxes contribute their selected option's name even with values such as `aria-selected="True"`. ([microsoft/playwright#43785](microsoft/playwright#43785), [microsoft/playwright#43787](microsoft/playwright#43787)) - `fix(selector generator): do not throw when css fallback path is not unique` — ambiguous matches in slotted web components report a useful strict-mode error instead of a `TypeError`. ([microsoft/playwright#43701](microsoft/playwright#43701), [microsoft/playwright#43705](microsoft/playwright#43705)) - `fix(frames): reject context waits when page closes` — pending operations on an iframe whose document has not loaded fail when its page closes instead of waiting indefinitely. ([microsoft/playwright#43647](microsoft/playwright#43647), [microsoft/playwright#43650](microsoft/playwright#43650)) - `fix(install): report missing dependencies for all browsers` — `playwright-cli install-browser` reports missing Linux dependencies across browsers in one pass, including package names for Vulkan and Graphene. ([microsoft/playwright#43747](microsoft/playwright#43747), [microsoft/playwright#43750](microsoft/playwright#43750)) ## 📦 Upgrading ```bash npm install -g @playwright/cli@0.1.24 ``` Co-authored-by: microsoft-playwright-automation[bot] <203992400+microsoft-playwright-automation[bot]@users.noreply.github.com>

([microsoft/playwright#43877](https://redirect.github.com/microsoft/playwright/pull/43877)) - `fix(chromium): account for tabs and toolbar in the new headless mode` — with `--headless`, Chrome and Edge now size their window to fit the viewport below the tab strip and toolbar, so videos from `browser_start_video` (opt-in via `--caps=devtools`) no longer lose the bottom of the page. ([microsoft/playwright#43904](https://redirect.github.com/microsoft/playwright/pull/43904)) - `fix(screenshot): support full-page SVG documents` — `browser_take_screenshot` with `fullPage: true` works on standalone SVG documents instead of waiting for a nonexistent HTML body ([microsoft/playwright#43962](https://redirect.github.com/microsoft/playwright/issues/43962)). ([microsoft/playwright#43972](https://redirect.github.com/microsoft/playwright/pull/43972)) ### [`v0.0.84`](https://redirect.github.com/microsoft/playwright-mcp/releases/tag/v0.0.84) [Compare Source](https://redirect.github.com/microsoft/playwright-mcp/compare/v0.0.83...v0.0.84) #### ✨ Highlights - **👥 Separate sessions in one browser** — work with multiple accounts without sharing their cookies or storage. `browser_tabs` with `action: "new"` now accepts `isolatedContext: "<name>"`: tabs with the same name share a context, while different names stay isolated. Omit it or use `"default"` for the default context. Cookie and storage tools operate on the current tab's context. ([microsoft/playwright#43087](https://redirect.github.com/microsoft/playwright/pull/43087)) - **🙈 Redact runtime values in URLs** ([#​1791](https://redirect.github.com/microsoft/playwright-mcp/issues/1791)) — session and grant values minted at runtime cannot be listed in a secrets file ahead of time. `--redact-url-params=access_token,code` (config `redactUrlParams`, env `PLAYWRIGHT_MCP_REDACT_URL_PARAMS`) replaces the named query and fragment parameter values with `<redacted>` in tool responses. Like `secrets`, this is a convenience, not a security feature. The extension also removes its connection token from the connect page URL after reading it. ([microsoft/playwright#43258](https://redirect.github.com/microsoft/playwright/pull/43258)) - **🔎 Bound find results** ([microsoft/playwright#42077](https://redirect.github.com/microsoft/playwright/issues/42077)) — common search terms no longer have to fill the response with every match. `browser_find` accepts a positive integer `maxResults`, returns the first matching items with their context, and reports the total match count. Omit it to keep returning all matches; ancestor paths are unchanged. ([microsoft/playwright#42947](https://redirect.github.com/microsoft/playwright/pull/42947)) - **🌐 Inspect requests across navigations** ([microsoft/playwright-cli#479](https://redirect.github.com/microsoft/playwright-cli/issues/479)) — requests from the previous page are no longer lost as soon as a flow navigates. `browser_network_requests` accepts `all: true` to include retained history, keeping up to 200 requests from earlier navigations. Request indexes stay stable across navigations for `browser_network_request`. `browser_console_messages` also reports counts consistent with its existing `all` option. ([microsoft/playwright#43526](https://redirect.github.com/microsoft/playwright/pull/43526)) - **🎯 Use locators in your language** ([#​1797](https://redirect.github.com/microsoft/playwright-mcp/issues/1797)) — element tools such as `browser_click` now accept JavaScript, Python, Java and C# locators in `target`, alongside snapshot refs and CSS selectors. Invalid targets get an actionable error, including a reminder to pass the bare ref rather than `button [ref=e5]`. ([microsoft/playwright#43539](https://redirect.github.com/microsoft/playwright/pull/43539)) - **📂 Skip unsupported workspace-root requests** ([#​1798](https://redirect.github.com/microsoft/playwright-mcp/issues/1798)) — clients that advertise roots but cannot answer `roots/list` can stall the first tool call. Pass `--ignore-roots` (config `ignoreRoots: true`, env `PLAYWRIGHT_MCP_IGNORE_ROOTS=true`) to skip that request and use the server's current working directory as the workspace root. ([microsoft/playwright#43532](https://redirect.github.com/microsoft/playwright/pull/43532)) - **🍪 Delete cookies by domain and path** — deleting a cookie by name no longer has to remove every cookie with that name. `browser_cookie_delete` (opt-in via `--caps=storage`) accepts optional `domain` and `path` filters to leave other domains and paths untouched. ([microsoft/playwright#43319](https://redirect.github.com/microsoft/playwright/pull/43319)) #### 🐛 Fixes - `fix(mcp): allow combining time, text and textGone in browser_wait_for` — when combined with a text condition, `time` is its timeout (capped at 30 seconds), not a delay before checking it. Supplying both `text` and `textGone` now waits for the first condition to happen, rather than both in sequence. ([microsoft/playwright#43011](https://redirect.github.com/microsoft/playwright/pull/43011)) - `fix(mcp): allow loopback hosts by default for all bind addresses` — HTTP clients can connect through `localhost`, `127.0.0.1` or `[::1]` regardless of the bind address. Other hosts still require `--allowed-hosts`; binding to `0.0.0.0` prints a usable localhost URL. ([microsoft/playwright#42993](https://redirect.github.com/microsoft/playwright/pull/42993)) - `fix(mcp): pass credentials from --proxy-server as proxy username/password` — credentials embedded in the proxy URL are now passed to the browser as proxy authentication settings. ([microsoft/playwright#43071](https://redirect.github.com/microsoft/playwright/pull/43071)) - `fix(mcp): race browser_navigate_back against modal states` — `browser_navigate_back` reports a dialog opened during history navigation instead of timing out. ([microsoft/playwright#43252](https://redirect.github.com/microsoft/playwright/pull/43252)) - `fix(mcp): normalize bare host URLs and loopback IP addresses` — `browser_navigate` handles scheme-less hosts with ports and uses HTTP for loopback addresses such as `127.0.0.1:3000` and `[::1]:3000`. ([microsoft/playwright#43264](https://redirect.github.com/microsoft/playwright/pull/43264)) - `fix(mcp): do not close the browser twice when the client disconnects` — stdio disconnects let the browser close gracefully instead of force-killing it through a second close request. Dashboard annotation processes also exit when their parent goes away. ([microsoft/playwright#43174](https://redirect.github.com/microsoft/playwright/pull/43174)) - `fix(mcp): give each isolated client its own idle timer` — with HTTP transport and `--isolated`, an idle client's context now expires even while another client keeps the shared browser busy. ([microsoft/playwright#43527](https://redirect.github.com/microsoft/playwright/pull/43527)) - `fix(mcp): apply route headers without bypassing origin filters` — `browser_route` (opt-in via `--caps=network`) matches added request header names case-insensitively, includes custom headers in mocked responses, and preserves origin filters and other routes when modifying request headers. ([microsoft/playwright#43227](https://redirect.github.com/microsoft/playwright/pull/43227), [microsoft/playwright#43244](https://redirect.github.com/microsoft/playwright/pull/43244), [microsoft/playwright#43637](https://redirect.github.com/microsoft/playwright/pull/43637)) - `fix(mcp): correct cookie filtering and missing-domain errors` — `browser_cookie_list` (opt-in via `--caps=storage`) matches domain and path boundaries instead of unrelated names such as `notexample.com` or `/apiary`. `browser_cookie_set` asks for an explicit `domain` when the current page has no hostname, such as `about:blank`. ([microsoft/playwright#43316](https://redirect.github.com/microsoft/playwright/pull/43316), [microsoft/playwright#43368](https://redirect.github.com/microsoft/playwright/pull/43368), [microsoft/playwright#43318](https://redirect.github.com/microsoft/playwright/pull/43318)) - `fix(mcp): accept Windows paths in browser_resume location` — `browser_resume` (opt-in via `--caps=devtools`) no longer mistakes a Windows drive-letter colon for the line-number separator. ([microsoft/playwright#43349](https://redirect.github.com/microsoft/playwright/pull/43349)) - `fix(mcp): report run-code route handler exceptions once and verbatim` — `browser_run_code_unsafe` reports a route handler's thrown value without duplicating it or wrapping non-Error values in another error. ([microsoft/playwright#43203](https://redirect.github.com/microsoft/playwright/pull/43203)) - `fix(extension): release debugger when attach completes after connection close` — disconnecting while `browser_tabs` attaches to a new tab no longer leaves that tab attached to the extension's debugger. ([microsoft/playwright#43025](https://redirect.github.com/microsoft/playwright/pull/43025)) - `fix(chromium): close pages that crashed before connecting over CDP` — connecting through `--cdp-endpoint` no longer stalls on an already crashed or discarded page; those pages are omitted from the tab list. ([microsoft/playwright#43075](https://redirect.github.com/microsoft/playwright/pull/43075)) - `fix(aria): skip text nodes that are not rendered` — `browser_snapshot` and accessible names omit unrendered text, including unslotted shadow-host text and text directly inside closed `<details>`. ([microsoft/playwright#43150](https://redirect.github.com/microsoft/playwright/pull/43150)) - `fix(a11y): treat inert elements and content outside of modal dialogs as hidden` — snapshots exclude inert content and content outside the topmost modal `<dialog>`. Click and fill actions wait for targets to stop being inert instead of silently misfiring. ([microsoft/playwright#43211](https://redirect.github.com/microsoft/playwright/pull/43211)) - `fix(aria): do not count whitespace-only contributors as name sources` — snapshots retain button names when whitespace around a hidden icon previously caused the name to disappear. ([microsoft/playwright#43317](https://redirect.github.com/microsoft/playwright/pull/43317)) - `fix(aria): resolve label references consistently` — snapshots and role locators recognize tab- or newline-separated label IDs and labels assigned through `ariaLabelledByElements`, while retaining attribute-based labels in older browsers. ([microsoft/playwright#43361](https://redirect.github.com/microsoft/playwright/pull/43361), [microsoft/playwright#43577](https://redirect.github.com/microsoft/playwright/pull/43577), [microsoft/playwright#43722](https://redirect.github.com/microsoft/playwright/pull/43722)) - `fix(aria): quote ~, .inf and .nan in aria snapshots` — YAML-like names remain strings rather than being parsed as null or special floating-point values. ([microsoft/playwright#43469](https://redirect.github.com/microsoft/playwright/pull/43469)) - `fix(aria): preserve iframe snapshots with fallback text` — snapshots retain an iframe's contents when the iframe element also contains fallback text. ([microsoft/playwright#43635](https://redirect.github.com/microsoft/playwright/pull/43635)) - `fix(aria): match mixed-case roles and states` — snapshots and role locators recognize mixed-case `role` and ARIA state values, including checked, pressed and expanded states. ([microsoft/playwright#43727](https://redirect.github.com/microsoft/playwright/pull/43727)) #### 📦 Upgrading Configs that use `@playwright/mcp@latest` pick this release up on the next client restart.
