REQUIRED: Allow this extension in Ollama
Ollama blocks browser extensions by default. You must set the environment variable OLLAMA_ORIGINS=chrome-extension://* to allow Chrome extensions. Without this step you get a 403 error.
Windows (recommended way via GUI):
  1. Install Ollama from ollama.com
  2. Quit Ollama completely (System Tray bottom-right → right-click Ollama icon → Quit)
  3. Press Win key, type environment variables, open "Edit the system environment variables"
  4. Click "Environment Variables..." button
  5. Under "User variables" click "New..." and enter:
    Name: OLLAMA_ORIGINS Value: chrome-extension://*
  6. Click OK three times to close all dialogs
  7. Start Ollama again (from Start Menu) — if Ollama autostarts, you may need to restart Windows for it to pick up the new variable
  8. Pull a model (open cmd or PowerShell):
    ollama pull llama3.2
  9. Reload this extension at chrome://extensions (click the reload icon)
Mac:
launchctl setenv OLLAMA_ORIGINS "chrome-extension://*"
Then quit Ollama from the menu bar and restart it.
Linux:
systemctl edit ollama.service # add under [Service]: Environment="OLLAMA_ORIGINS=chrome-extension://*" # then: systemctl daemon-reload && systemctl restart ollama

  • Did Ollama actually restart? The new variable only takes effect after a full restart. On Windows, restart your PC to be sure.
  • Verify the variable was set: Open a NEW cmd/PowerShell window and run echo %OLLAMA_ORIGINS% — must print chrome-extension://*
  • Direct test: Open http://127.0.0.1:11434/api/tags in browser — JSON response = Ollama is running
  • Try the wildcard for testing only: set value to * instead of chrome-extension://*
  • Ollama running as Windows Service? Open services.msc → find Ollama → Restart
  • Firewall/Antivirus blocking port 11434? Add an exception
