  • Version 1.4.4

    Released Aug 11, 2026 - 15.11 MB
    Works with firefox 152.0 and later
    Version 1.4.4 resyncs the Firefox/Zen port with the complete inherited OpenAI extension distribution from packaged version 1.2.27236.6274. It keeps the newer ChatGPT website integration alongside the Firefox CDP compatibility layer, preserves the upstream Ask ChatGPT context-menu item, and includes the upstream auth-state fix that prevents a null auth notification from blanking the sidebar. This build was regression-tested for open-tab mentions, highlighted-text handoff, Ask ChatGPT context menus, timestamped YouTube captions, browser-history search, and browser/desktop thread handoff.
