🟢 The one failure is a known pre-existing flake — this PR looks clear

Hi, I'm the Playwright bot and I took a look at the failing CI.

[firefox] › mcp/cli-session.spec.ts:54 › idle timeout shuts the session down on @mcp-windows-latest-firefox fails with the same Expected substring: "(no browsers)" assertion on main and on a dozen unrelated PRs — including commit 1820528, which is this PR's own base. It has failed 16 of 47 runs (34%) on that bot, and never once on any of the other 12 MCP bots.

Details

Pre-existing flake / infra

The 7 flaky tests in "tests 1" all passed on retry and none of them touch Firefox request interception or storage state, so there's nothing to triage there.

Triaged by the Playwright bot - agent run

Pavel Feldman (pavelfeldman) added a commit to microsoft/playwright-cli that referenced this pull request Sep 18, 2026
## ✨ Highlights

- **🎬 Smooth 60 fps, styleable videos** — `video-start --fps=60` records
smooth 60 fps videos instead of the default 25, and `video-start
--cursor` renders an animated mouse cursor that travels to each action
point and stays visible between actions. `video-show-actions` takes
`--point-style`, `--highlight-style` and `--title-style` CSS
declarations; the action point marker and the target highlight are now
only shown when styled.
([microsoft/playwright#42752](microsoft/playwright#42752),
[microsoft/playwright#42758](microsoft/playwright#42758))
- **🧰 WebMCP tools show up in the snapshot** — the tools a page
registers are listed at the top of the page snapshot with their
descriptions and input schemas, so `webmcp-call` can be used without
running `webmcp-list` first. Set `webmcp: false` in the config file (env
`PLAYWRIGHT_MCP_WEBMCP=false`) to stop collecting page-registered tools.
([microsoft/playwright#42671](microsoft/playwright#42671))
- **🌗 Switch between light and dark color scheme**
([microsoft/playwright#42243](microsoft/playwright#42243))
— an agent working on a dark theme had no way to see it mid-session. New
`set-color-scheme`, `set-reduced-motion`, `set-forced-colors`,
`set-contrast` and `set-media` commands emulate media features on the
fly, and the matching `clear-*` commands reset them.
([microsoft/playwright#42668](microsoft/playwright#42668))
- **📁 Absolute paths in results**
([microsoft/playwright#42497](microsoft/playwright#42497))
— links to snapshots, screenshots, console logs and downloads are
relative to the working directory, which a consumer without one cannot
resolve. Set `filePaths: "absolute"` in the config file (env
`PLAYWRIGHT_MCP_FILE_PATHS=absolute`) to get absolute paths instead.
([microsoft/playwright#42673](microsoft/playwright#42673))

## 🐛 Fixes

- `fix(chromium): bypass service workers on the storage state page` —
`state-save` no longer runs the site's own scripts, or fails when they
redirect, for origins with an active service worker
([microsoft/playwright#42656](microsoft/playwright#42656)).
([#42664](microsoft/playwright#42664),
[#42741](microsoft/playwright#42741))
- `fix(mcp): keep upload modal, skip short secrets and bad headers` — a
failed `upload` keeps the file chooser open so it can be retried,
secrets shorter than 4 characters no longer rewrite the whole output
with `<secret>` markers, and `route` ignores header lines that have no
name. ([#42713](microsoft/playwright#42713))

## 📦 Upgrading

```bash
npm install -g @playwright/cli@0.1.21
```
Pavel Feldman (pavelfeldman) added a commit to microsoft/playwright-mcp that referenced this pull request Sep 18, 2026
## ✨ Highlights

- **🧰 WebMCP tools become real MCP tools** — the tools a page registers
through the [WebMCP](https://webmachinelearning.github.io/webmcp/) API
now show up right in the tool list as `webmcp_<tool>`, with the page's
own input schema and annotations, so an agent can call them directly and
let the page do the work instead of driving its UI. The list follows the
current tab, and clients get a `tools/list_changed` notification when it
changes. This replaces `browser_webmcp_list` / `browser_webmcp_call`
from v0.0.81, which are no longer exposed over MCP. Tool names,
descriptions, schemas and results come from the page, so treat them as
untrusted input. Pass `--no-webmcp` (config `webmcp: false`, env
`PLAYWRIGHT_MCP_WEBMCP=false`) to opt out. WebMCP is experimental, see
[WebMCP in Chrome](https://developer.chrome.com/docs/ai/webmcp) for how
to enable it.
([microsoft/playwright#42671](microsoft/playwright#42671))
- **🌗 Switch between light and dark color scheme**
([microsoft/playwright#42243](microsoft/playwright#42243))
— an agent working on a dark theme had no way to see it mid-session. The
new **`browser_emulate_media`** tool emulates media features on the fly:
`colorScheme`, `reducedMotion`, `forcedColors`, `contrast` and the
`media` type (screen / print). Omitted parameters are left unchanged,
`null` clears an override.
([microsoft/playwright#42668](microsoft/playwright#42668))
- **📁 Absolute paths in results**
([microsoft/playwright#42497](microsoft/playwright#42497))
— links to snapshots, screenshots, console logs and downloads are
relative to the workspace root, which a client without one cannot
resolve. Pass `--file-paths=absolute` (config `filePaths: "absolute"`,
env `PLAYWRIGHT_MCP_FILE_PATHS=absolute`) to get absolute paths instead.
([microsoft/playwright#42673](microsoft/playwright#42673))

## 🐛 Fixes

- `fix(mcp): keep upload modal and reject bad headers` — a failed
`browser_file_upload` (e.g. a missing file) reports the error and keeps
the file chooser open so it can be retried, and `browser_route` (opt-in
via `--caps=network`) returns an error for a header that is not in the
`Name: Value` form instead of setting a header named `""`.
([microsoft/playwright#42713](microsoft/playwright#42713))
- `fix(chromium): bypass service workers on the storage state page` —
`browser_storage_state` (opt-in via `--caps=storage`) no longer runs the
site's own scripts, or fails when they redirect, for origins with an
active service worker
([microsoft/playwright#42656](microsoft/playwright#42656)).
([microsoft/playwright#42664](microsoft/playwright#42664),
