Firefox is getting a major redesign with one-click controls to disable all AI features

Mozilla is redesigning Firefox under Project Nova with a refreshed interface and more customizable browsing tools.

A new Settings toggle will let users disable all current and future AI features in one click, giving clearer privacy control.

The update also improves access to tab management features like tab groups, split view, vertical tabs, and compact mode.

Firefox 151 adds Web Serial API support and PDF merging, reducing the need for separate apps.
