Extension Metadata

About this extension
Firefox port of the "Kimi WebBridge" Chrome extension (v1.11.6). The extension connects to the local Kimi WebBridge daemon (ws://127.0.0.1:10086) and executes browser commands in Firefox: navigating, reading pages (snapshot with @e refs), clicking, filling forms, running JavaScript, screenshots, network monitoring, and more.
  • Firefox 140 or newer
  • the Kimi WebBridge daemon running on the same machine


Firefox does not provide the Chrome debugger/CDP interface. As a result:
  • upload: not available (WebExtensions cannot set local files on file inputs)
  • cdp (raw passthrough): not available
  • network: requests, status codes and headers are captured, but no response bodies
  • save_as_pdf: the PDF is written directly to the Firefox download folder; returning file path/bytes to the daemon is not possible
  • send_keys / mouse_click: synthetic DOM events (event.isTrusted = false); sites with strict isTrusted checks (some banking portals, captchas) require manual interaction
  • screenshot: the target tab is briefly brought to the foreground; element screenshots are cropped from the viewport capture

All other tools (navigate, find_tab, snapshot, click, fill, evaluate, key_type, list_tabs, close_tab, close_session) behave like the Chrome version.
