Mozilla Firefox vs Google Chrome

Mozilla Firefox: what it's good at

Firefox is the last major browser not built on Google's Chromium engine, developed by the non-profit Mozilla Foundation. It offers strong tracking protection on by default, deep customisation, and genuinely excellent built-in developer tools.

• Independent Gecko rendering engine
• Enhanced tracking protection by default
• Extensive extension ecosystem
• First-class developer tools

Google Chrome: what it's good at

Chrome is the browser most of the web is tested against, which in practice means the fewest compatibility surprises. It offers the largest extension library, tight Google account sync, and consistently fast JavaScript performance.

• Broadest website compatibility
• Largest extension catalogue
• Sync across all your devices
• Frequent automatic security updates

Which should you choose?

Both are free, so the honest answer is that you can install either and decide for yourself — that is the advantage of free software over a paid trial.

Both run on Windows, macOS, Linux, Android, iOS. If open source matters to you, Mozilla Firefox publishes its source code and Google Chrome does not.

We deliberately do not publish a star rating for either. We have no way to verify a rating that would be honest at scale, and an invented one would be worse than none — so we give you the facts and let you decide.
