At a time when major browser vendors are racing to integrate AI features, Mozilla has taken a different approach by returning the choice to users. Mozilla has officially rolled out the Firefox148.0 version update globally. The most notable highlight of this update is the introduction of an "AI kill switch," allowing users to completely disable all built-in AI experiences in the settings.

AIbase reports that with the ongoing trend of making browsers "AI-powered," many users have been troubled by overly integrated AI plugins. Firefox 148 has specifically created an "AI Control" section in the settings interface, where users can not only manage various AI-enhanced features but also clear them all with one click. This user-centric, privacy-focused approach makes Firefox stand out notably in the browser market of 2026.

In addition to strong control over AI, the new version has also refined productivity tools. On the Windows platform, the previously reported "image drag and drop" bug has been fixed. Now, when you drag a downloaded image directly from the browser into Adobe Illustrator, it will correctly insert the image itself instead of a link. Meanwhile, the translation feature has also seen significant expansion, adding bidirectional translation for Traditional Chinese and support for Vietnamese, further breaking down language barriers when browsing web pages.

Notably, this update also marks the end of an era. The concurrently released Firefox 115.33 will be the last security update supporting Windows 7, 8, and 8.1 systems. Starting in February 2026, Mozilla will completely stop maintaining these older systems. For users still relying on outdated devices, this means upgrading hardware or switching to Windows 10 or higher systems is now imminent.
