Editor's Verdict
Editor's VerdictIf you care about having an assistant that can actually interact with your tabs, click around the web for you, and dig up factual information with clear citations, Comet Browser blows Firefox out of the water. Its agentic browsing is not just a buzzword, you can literally tell it what to do and it will take actions for you, even connecting with your email and calendar. That's something Firefox doesn't even attempt.
Firefox's main play is privacy, but you're trading away extension support and site compatibility. A lot of sites just don't work right, and you'll miss out on the huge world of Chrome extensions. Most people who pick Firefox end up needing a second browser anyway to fill those gaps.
If you want an actual next-level assistant baked into your browser for research or shopping, grab Comet. If your top priority is privacy and you're willing to put up with broken sites and fewer extensions, Firefox is fine, but you're not getting anything like Comet's agentic features. For real interactive browsing, Comet is the obvious pick.
