FREE Browser vs Mozilla Firefox

FREE Browser is a free, open-source Android web browser focused on privacy controls. The project describes it as having no trackers and no unnecessary permissions. Its built-in blocker uses the StevenBlack host list; users can choose a list and add domains. Fingerprinting protection can be switched on or off. A cookie-banner blocker applies Mozilla Cookie Banner Rules, requiring JavaScript and not handling rules in child windows. Site controls let users set JavaScript, cookies, and DOM storage by domain or bookmark, and change ad blocking, fingerprinting protection, and desktop mode per tab. The browser supports simple Greasemonkey-style scripts, with @match required; @run-at and @name work, while @include, @exclude, and @grant do not. Navigation includes unlimited tabs, in-page search, selected-text web search, PDF saving, and opening links in other apps. It can back up and restore databases, bookmarks, and preferences to Documents/browser_backup. F-Droid lists version 3.5.0.159 for Android 10 or newer.

Mozilla Firefox is a free, open-source web browser that uses the Gecko engine. It is available on Windows, macOS, Linux, iOS, Android, and as a browser extension, and its download page lists availability in more than 90 languages. Standard tracking protection and built-in ad blocking are included. Total Cookie Protection isolates cookies so they cannot follow users between websites, while Tab Groups organize open tabs by project, mood, or task. A Mozilla account can sync bookmarks, passwords, and open tabs across devices. Firefox also offers access to multiple AI chatbots in one place, letting users choose whether to use them. Thousands of free extensions are available through addons.mozilla.org. Mozilla’s privacy notice says browsing history, form data, temporary files, and cookies are processed on the device unless stated otherwise. Automated translation and PDF alt-text suggestions use downloaded language models locally; Firefox says those features do not send page content, PDFs, images, or tab URLs to Mozilla. Firefox is listed at free.
