Brave vs Firefox: Which Privacy Browser Is Best?

Quick Verdict

Both Brave and Firefox are excellent privacy browsers. Choose Brave if you’re coming from Chrome and want the easiest transition with built-in ad blocking. Choose Firefox if you value true independence from Big Tech and want to support a non-profit organization.

Overview

Brave

Built on Chromium with aggressive privacy defaults, Brave blocks ads and trackers out of the box. Founded by Brendan Eich (JavaScript creator, Mozilla co-founder), it aims to fix the broken web advertising model.

Firefox

The only major browser from a non-profit organization, Firefox has championed the open web since 2004. It’s truly independent from Google, Microsoft, and Apple.
