Firefox 157 is rolling out a redesigned interface across desktop and mobile as Mozilla tries to reach people beyond its privacy-conscious and open-web base. The update brings back compact mode, expands customization and adopts a more modern visual language aligned with operating systems.
Firefox chief Ajit Varma says most users do not distinguish Gecko, Chromium and Chrome, so arguments about browser-engine competition are insufficient for mass adoption. Mozilla wants Firefox to win on everyday experience while retaining an independent engine. The company says mobile browser-choice screens in Europe and Chrome’s removal of older extension support have created moments when more people consider switching.
Mozilla is also investing in management and data-loss-prevention tools for schools and enterprises. On AI, Firefox exposes top-level controls and lets users disable features rather than tying the browser to one assistant. The redesign does not solve Mozilla’s dependence on Google search revenue or the inertia of preinstalled browsers, but it gives potential switchers a product-focused reason to evaluate Firefox.
