Firefox rolls out redesigned interface to all users with FX 157
Mozilla has released a new visual design for Firefox to all desktop and mobile users via the FX 157 update, following months of testing in its Nightly channel. The refresh updates colors, icons and themes across tabs, toolbars, the New Tab page and Private Browsing, and brings back Compact Mode along with a new theme picker.
GoKawiil's interpretation of the reporting above, not reported fact.
The update suggests Mozilla is trying to modernize Firefox's look to feel more competitive against rivals while retaining loyal users who value customization, according to the company's own framing of the changes. Restoring Compact Mode after user feedback indicates Mozilla is responsive to community input during redesigns, which could help ease the transition for longtime users wary of interface changes.
- Firefox's new design is now live for all desktop and mobile users starting with FX 157.
- Compact Mode returns, letting users shrink tabs and toolbars for more screen space.
- A new theme picker and refreshed icons/colors apply across tabs, toolbars, New Tab and Private Browsing.
