Firefox alternatives: 6 apps ranked by verified data

Facts checked Oct 25, 2026AppBreakup editorialHow we rank

We ranked 6 alternatives by how directly each one replaces Firefox, then by reviews, real visits and how recently each app's facts were checked against its own website. LibreWolf currently ranks first.
