Google originally removed Adblock Plus because it interfered with other apps. So by implementing the same technology into Adblock Browser for Android, it could silo the experience and immediately nullify the issue. The app itself runs on a version of Mozilla's open-source Firefox Android browser, which offers stability and a sense of familiarity but can also block ads and speed up browsing. However, support for third-party extensions and Firefox's synchronization features are lost as a result.
The launch comes just as European mobile carriers are said to be toying with the idea of blocking ads on customer phones to get a cut of Google's ad revenue. The search giant won't be happy with the return of Adblock Plus, but seeing as it already allows Chrome users to download the extension via the browser's Web Store, we imagine it will begrudgingly remain neutral. The app has yet to reach the Play Store, so users are encouraged become testers by signing up to Adblock Plus' Google+ community and download it once it becomes available.
Update: Tired of waiting for the app to go live on the Play Store, the team is now offering a direct download for Adblock Browser. You can find it via this link.
