filtering rules and features that sap their speed and hog your computer or device’s CPU, memory, and
storage. Adblock Fast executes a mere 12 optimized filtering rules to accelerate pages 8x more but
consume 6x less computing resources than other ad blockers do.

experiences in the universe.

What is Adblock Fast?

Adblock Fast is a faster ad blocker for desktop computers and mobile browsers.

When will Adblock Fast be available on [insert platform here]?

Adblock Fast is available for Windows 7 and up, Android 5.0 and up with Samsung Internet 4.0 and up,
iOS 9 and up on 64-bit devices (iPhone 5s and up and iPad mini 2 and up), and the Chrome and
Opera desktop browsers. Follow us on Facebook or

Where does Adblock Fast’s filtering ruleset come from?

Adblock Fast’s ruleset is derived from EasyList and that of
Bluhell Firewall.

Why does Adblock Fast require [insert permission here] at install time?

Like all (functional) ad blockers, Adblock Fast prompts you for the permissions required to block ad
requests by intercepting HTTP traffic and to hide ad elements by injecting CSS and JavaScript into
visited pages.

How do Adblock Fast’s mobile blocking modes work?

Adblock Fast for mobile lets you choose your blocking mode. If you tap the Fast button or link
(or have previously installed the app), our default filtering rules are activated. If you tap the
Faster button or link, a more comprehensive, up-to-date set of filtering rules are activated;
Faster is an experimental mode that uses what should be an unnoticeable amount of your background
bandwidth to anonymously crawl common websites (no cookies or any other personal
info are used) and help detect new ad domains to filter.

How can Adblock Fast for Windows be uninstalled?

Open the Start menu, go to Settings > Apps > Apps & features, choose the
Adblock Fast app, then press the Uninstall button.
