Just as webpages grew bloated with ads, so too have ad blockers grown bloated with little-used 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.

Adblock Fast installs a button in your browser’s toolbar. To show the button:

1. click the extensions (puzzle) button in your toolbar then
2. click the pin button next to the extension listing.

The button indicates the status of the site and page you’re on:

Ads are being blocked on the site and ads were found on the page.

Ads are being blocked on the site, but no ads were found on the page.

Ads aren’t being blocked on the site, but ads were found on the page.

Ads aren’t being blocked on the site and no ads were found on the page.

If Adblock Fast is interfering with the behavior of the page, you can click the button to unblock ads. Your choice will be remembered whenever you go back to the site.

If you have any questions or comments, you can follow and message us on Facebook or on Twitter.

Adblock Fast was created and is maintained by Rocketship, an award-winning app studio whose mission is to design and develop the finest desktop, mobile, and web experiences in the universe.

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

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 on Twitter for news about additional platform availability.

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

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.

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.

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