Firefox 148 drops a dedicated AI Controls panel that lets you block every built‑in generative‑AI feature with a single toggle or fine‑tune individual tools. The master switch disables UI prompts, stops AI model downloads, and shields your data, while still letting power users keep the features they need. It’s a privacy‑first move that answers growing demand for a clear “off” option.
What the AI Controls Panel Does
Master Switch for All AI Enhancements
Turning on the “Block AI enhancements” toggle hides AI entry points, suppresses promotional nudges, and deletes locally stored AI models, preventing them from consuming resources.
Granular Controls for Built‑In AI Tools
Below the master switch you can manage five first‑party AI capabilities:
- AI‑assisted translations – on‑the‑fly language conversion powered by generative models.
- Alt‑text generation for PDFs – automatic accessibility descriptions for embedded images.
- AI‑enhanced tab grouping – smart suggestions for grouping and naming tabs.
- Link previews “key points” – concise summaries that appear before you click a link.
- Sidebar chatbot – an optional panel that can connect to third‑party chat services.
Each option can be set to “Available,” “Enabled,” or “Blocked,” giving you precise control without digging through hidden menus.
Why the One‑Click Switch Matters Now
The browser market is racing to embed AI everywhere, from omnibox suggestions to in‑page assistants. Firefox’s privacy‑focused audience has pushed back on opaque AI rollouts, and the new toggle offers a straightforward way to keep a lean browsing experience while still allowing selective AI use.
Enterprise Benefits of a Global AI Toggle
IT admins can enforce a baseline of data minimization across fleets with a single configuration change. You can disable all AI features for employees while re‑enabling specific tools on a case‑by‑case basis, simplifying policy management.

Implications for the Browser Landscape
The AI kill switch could set a precedent. If a major browser can bundle generative AI while still offering a clean opt‑out, other vendors may feel pressure to follow suit. It highlights the tension between rapid AI feature rollouts and user‑centric privacy controls.
Practical Takeaway for Users and Teams
From a systems‑admin perspective, the toggle provides a sanity check. You can globally disable AI features with one policy flag, then selectively enable useful tools—like AI‑assisted translations for foreign‑language documentation—without exposing the entire suite.
What’s Next for Firefox Users
Mozilla frames the AI Controls panel as a “product‑level promise” that balances ongoing AI research with user choice. While the master toggle offers an immediate “off” position, the company will continue evolving AI capabilities behind the scenes. For now, you can enjoy a lean, AI‑free browsing experience or enable select AI‑enhanced workflows as you see fit.
