Mozilla is experimenting with a new AI-powered "smart window" for its Firefox browser, offering users the ability to dock an AI assistant of their choosing alongside their tabs — but only for those who deliberately choose to switch it on.
An Opt-In Approach to AI
Unlike many browsers that have baked artificial intelligence directly into the core experience, Mozilla is taking a more cautious route. The new feature is entirely optional, requiring users to actively enable it rather than having it foisted upon them by default. Those who prefer a cleaner, distraction-free browser can leave the tool switched off and never encounter it.
The smart window places an AI assistant panel next to the user's open tabs, allowing quick access without the need to jump between separate applications or browser windows. Crucially, the feature includes a simple toggle so it can be disabled at any time.
Firefox is betting that giving users control over AI — not forcing it on them — is the smarter play.
Choice and Control at the Core
One of the standout aspects of Mozilla's design is flexibility over which assistant powers the experience. Rather than locking users into a single proprietary system, the smart window lets people select the AI service they prefer, reflecting Mozilla's long-standing emphasis on user autonomy and open choice.
The move fits neatly into the browser maker's broader identity as a privacy-conscious alternative to larger rivals. By making AI a feature users summon rather than one that arrives uninvited, Mozilla is positioning itself against competitors that have aggressively integrated generative tools.
Key elements of the feature include:
- An AI assistant panel docked beside browser tabs
- The ability to pick which assistant to use
- A toggle to turn the feature off entirely
As AI becomes an increasingly common fixture across web browsers, Mozilla's experiment underscores a growing debate over how much artificial intelligence users actually want built into their everyday tools — and whether it should be a default setting or a deliberate decision.
