What Adblock Fast 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 the 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, and on iOS it blocks ads in Safari. The maker lists Windows 7 and later support and a Chrome desktop extension; the repository marks Opera support as discontinued. In Chrome, users can unblock ads for a site from the toolbar button, and that choice is remembered when they return. Mobile users can select the default Fast rules or an experimental Faster mode with more comprehensive, current 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.
