Firefox 155 Released: AI Smart Window & Key Linux Fixes

Mozilla has officially released Firefox 155, an update that continues the browser’s push into generative features while refining the user experience for dedicated enthusiasts. The headline addition is the broader rollout of the AI-powered Smart Window, now accessible to users in the USA, Canada, and France.

The Expansion of AI-Powered Smart Window

The Smart Window feature represents Mozilla’s commitment to integrating AI directly into the browser workflow. By using localized intelligence, the tool helps users manage information more efficiently. For users in the newly added regions, this update means a more intuitive way to handle research and browsing tasks without leaving the active window. This shift signifies Mozilla’s broader strategy to compete with Chromium-based browsers by offering smarter, privacy-conscious AI tools.

Crucial Linux and Usability Enhancements

Beyond the AI additions, Firefox 155 packs several under-the-hood refinements that matter to the daily driver. Linux users, in particular, will benefit from specific performance patches that address long-standing stability issues, ensuring a smoother integration with modern desktop environments.

Key Changes in Firefox 155

AI Smart Window: Expanded regional availability for users in the USA, Canada, and France.
Linux Stability: Targeted fixes for better system performance and responsiveness on various distributions.
Tracker Transparency: Updated blocked tracker counts to give users more granular insight into their privacy.
UI Customization: Improved container reordering, allowing power users to better organize their browsing sessions.

These updates reinforce the browser’s reputation for being highly customizable. The ability to reorder containers is a welcome quality-of-life change for those who rely on Firefox’s multi-account capabilities to keep work, personal, and project-based sessions isolated.

The release of Firefox 155 demonstrates that Mozilla can balance experimental AI features with the fundamental performance fixes that the Linux community demands.

If you are running Firefox on a desktop distribution, expect your package manager to pick up these improvements shortly. This update serves as a reminder that while AI is the current industry trend, Mozilla remains laser-focused on the utility and privacy-first architecture that loyal users have come to expect.
