Mozilla has launched Firefox 154, marking the last monthly release before the browser transitions to a faster bi-weekly schedule beginning in September. This update brings several updates including AI features, enhanced translation capabilities, and improved video seeking performance across all operating systems.
Key Features of Firefox 154
-
AI Enhancements: Users now have quicker access to AI controls through a new feature in the address bar. Simply type “Manage AI” to find the related quick action.

Improved Translations: The full-page translation function has been enhanced to translate
<iframe>content and now includes language detection for all page loads, creating a better experience for users seeking translations. -
Interface Changes: The Firefox View icon has been removed from new profiles or those that haven’t interacted with it recently, though it can be added back manually.
Additional Updates
- Text selection in PDFs conforms to the OS’s high-contrast setting for a consistent viewing experience.

Video Seeking Improvements
With the Firefox 154 release, video seeking has been notably enhanced.
