Firefox 151 ships with a refreshed New Tab page now called Firefox Home, featuring a rounded pill-shaped search bar inspired by the upcoming Nova redesign and new background options. Other highlights include PDF merging support in the built-in PDF viewer, a session-clearing flame button in Private Browsing Mode, Linux profile backup support, improved fingerprinting protection in Standard Enhanced Tracking Protection, and a more compact Settings page layout.
