- Server rejects new extension (code 4002) if existing has active tabs
- Idle extensions (no tabs) can still be replaced
- Extension properly enters polling mode when rejected during handshake
- /extension/status now returns activeTargets count for smarter reconnection
Fixes 'no low surrogate in string' API error when page content contains
malformed Unicode characters. Uses toWellFormed() on Node.js 20+ with
graceful fallback on older versions.
Uses elementsFromPoint() to check if element is blocked by opaque
overlays (modals, cookie banners, etc.). Skips elements where an
opaque element with pointer-events appears above the target in
the stacking order.
Correctly shows only visible, interactable elements.
- Connect WS at extension startup via maintainConnection() loop
- Auto-retry every 5 seconds silently (no connecting badge)
- Never disconnect WS based on tab count
- Rename ConnectionState 'disconnected' to 'idle', remove global 'connecting'
- Fix race condition with tabGroupQueue for syncTabGroup/disconnectEverything/onTabUpdated
- Add auto-create initial tab when Playwright connects (PLAYWRITER_AUTO_ENABLE env var)
- Add test for auto-create feature
- Add build-resources.ts script to generate markdown API docs
- Resources now use https://playwriter.dev/resources/*.md URLs
- Output to both playwriter/dist/ and website/public/resources/
- Simplify mcp.ts resource handlers to read pre-built files
- Add bippy library for React fiber introspection
- Create build-bippy.ts and build-selector-generator.ts using Bun.build
- Use CDP Runtime.evaluate instead of addScriptTag to bypass CSP
- Add getReactSource utility function exposed in MCP VMContext
- Works on local React dev servers with JSX transform (not production builds)
