Extension Metadata

About this extension
Ossi Browser Bridge for Firefox lets Codex work in your regular Firefox session only when you explicitly request it.

Features:
  • Navigate, read pages, click, type into focused fields, scroll, use browser history, reload, and capture visible-tab screenshots.
  • Reuse existing signed-in Firefox sessions without exporting cookies, history, saved passwords, or Firefox profiles.
  • Pair the extension with the local Firefox Codex plugin through authenticated loopback WebSockets.
  • Grant website access per exact public HTTP(S) origin for the current Codex task.
  • Keep pre-existing tabs and windows user-owned and restrict automatic cleanup to task-created browser state.

Requirements:
  • Windows desktop
  • Firefox 142 or newer
  • Codex with plugin support
  • The public firefox@firefox-local Codex plugin

This is an experimental preview. The extension has no native host, separate bridge installation, publisher-operated server, analytics, telemetry, or advertising.
