Mozilla launched Firefox Focus on iOS past year with enhanced privacy features, and now it's available on Android. The Android version has additional features compared to the previously released iOS version: a counter listing the number of ads blocked so far, an option to disable the tracker blocker, and a notification reminder that Firefox is still running.
The browser is intentionally barebones.
"With today's release, Firefox uses up to four processes to run web page content across all open tabs". In addition to Firefox, the company now also offers Firefox Focus, a browser dedicated to user privacy that by default blocks many web trackers, including analytics, social, and advertising. Browsers are increasingly packing in anonymous modes that don't let others on the web track your activity, and Apple and Google say they're going to block videos that autoplay. With Firefox Focus, privacy and ad-tracker blocking are automatic.
Like the iOS version, Firefox Focus remains a minimalistic browser experience.
Disable tracker blocker - For sites that are not loading correctly, you can disable the tracker blocker to quickly take care of it and get back to where you've left off. Moreover from security and privacy, these features also support the data usage. One thing you might want to remember is that Firefox Focus does not utilize the tabs, like you would find on normal Firefox browsers.
What we mean by this is that the Android version is also focused on blocking a lot of the advertisements that you might come across on your browser. If you do encounter a site that completely disallows access with ad-blockers enabled, you can shut that off in the menu. Bermes said that Firefox Focus uses the default Android WebView, which uses Webkit.
Focus earned a "good" rating in PCMag's review of the iOS version.
Firefox Focus will also follow a different release cadence than the existing Firefox browser.
