Adblock Fast · Covina, California, United States
What it is
Adblock Fast is a free ad blocker for desktop computers and mobile browsers. It uses 12 optimized filtering rules derived from EasyList and Bluhell Firewall; the maker says these rules are designed to speed page loading while using less CPU, memory, and storage. On Android, it blocks ads in Samsung Internet 4.0 and later, while on iOS it works in Safari. The maker lists support for Windows 7 and later and offers a Chrome desktop extension; Opera support is marked discontinued in the repository. In Chrome, the toolbar button can turn off blocking for a particular site, and the choice is remembered for later visits. Mobile users can choose the default Fast rules or an experimental Faster mode with more comprehensive, up-to-date rules. The maker says Faster mode anonymously crawls common websites using background bandwidth without cookies or other personal information. The blocker intercepts HTTP traffic and injects CSS and JavaScript into visited pages to block requests and hide ad elements. Its code is open source under the GNU General Public License version 3 or later, subject to listed exceptions.
