Editor's Verdict

Editor's Verdict

Arc Browser is the clear pick if you want full compatibility with Chrome extensions and websites. Since it's built on Chromium, everything just works, and you get all the productivity-focused features without running into weird website glitches or missing extension support.

Firefox is only worth considering if privacy is your absolute top concern and you're willing to deal with fewer extensions and more sites breaking or not rendering right. Most people who use Firefox end up having to keep a Chromium browser around anyway just to get things done.

So unless you're a hardcore privacy purist who's fine with constant compatibility hassles, Arc is the better choice for pretty much everyone else.
