Adblock Fast vs AdLock

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 intended 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 works in Safari. The maker lists support for Windows 7 and later and a Chrome desktop extension; the repository marks Opera support as discontinued. In Chrome, the toolbar button can disable blocking for a site, and the choice is remembered when a user returns. Mobile users can choose 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. The app does not block ads in other Android or iOS apps.

AdLock blocks ads and helps filter tracking and malicious activity across Windows, macOS, iOS and Android, with Android TV also listed. It blocks ad types by default and does not participate in acceptable ads; users can allow ads on selected websites or apps. Other protections include blocking tracking scripts, malware, malicious requests and redirects, plus filtering HTTP and HTTPS connections. Users can add custom filter lists and block cookie popups. Browser coverage includes Chrome, Safari and Firefox, as well as major browsers generally. AdLock says it uses few device resources, can save mobile data and can extend battery life. Free browser extensions are available, and standalone applications offer free trials. The free plan and paid options coexist: plans are $9.95 a month, $39.50 a year, or $15.99 a year when billed every five years. Paid plans cover five devices and include a 30-day money-back guarantee. The company lists 24/7 technical support and is based in Bratislava, Slovakia.
