  • Linux users and anyone who wants a non-Chromium engine to avoid single-vendor dependence

How the products differ

Google Chrome: Chrome suits people already in the Google ecosystem who want a free browser on every device, a huge extension store and steady security updates. The trade-offs are privacy terms that rest on Google's general policy, and Google's phase-out of Manifest V2 extensions, which ended support for some older ad blockers.

Mozilla Firefox: Firefox suits people who want a free, open-source browser with tracking protection built in and no dependence on the Chromium engine. The trade-offs are a desktop share of about 6.3%, so sites may be tuned for Chrome first, and the 2025 terms-of-use controversy that dented some users' trust.
