About this extension
ContextOS keeps decisions and constraints in sync across the AI tools you already use. This Firefox add-on is the browser half: opt-in capture from chatgpt.com, claude.ai, Gemini, Google AI Studio, and grok.com into your local ContextOS graph on this computer.
Requires the free ContextOS desktop app on the same PC (https://contextos.ca/download). Open the app and click Sync now once so the Firefox helper is registered. Then open the ContextOS sidebar, turn on each site you want, and approve Firefox’s permission prompt. Capture stays off until you enable a site.
The add-on talks only to ContextOS on this machine (native messaging and localhost). It does not upload chats to contextos.ca.
