Gemini Tools
Extension Actions
Allows you to customize the Gemini web app beyond the limited settings exposed to the user.
Gemini Tools gives you more control over how Gemini behaves in your browser.
It helps preserve the model you intentionally selected and only intervenes when Gemini appears to switch models on its own. The extension is designed to stay out of your way and respect manual user choices.

Notes
This extension depends on Gemini’s web UI structure. If Google changes the interface, behavior may require updates. If your account does not have access to a specific model, the extension cannot force unavailable modes.
