6x less disk, CPU, and
memory consumption

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 disk space, CPU cycles, and memory. Adblock Fast runs a mere 7 optimized filtering rules to accelerate pages 8x more but consume 6x less system resources than other ad blockers do.

  4. CPU use was measured in the Chrome browser on September 1st, 2015 by (1) enabling each extension, (2) clearing the browser’s cache before each trial, (3) loading the homepage of each of Alexa’s top 10 news websites over three trials, (4) recording the peak CPU percentage shown by the Task Manager, and (5) calculating the mean percentage for each extension.

Owner’s manual

Adblock Fast is so fast that even reading the effing manual takes no time flat. Here’s everything you need to know.

In iOS

Adblock Fast blocks ads in Safari not in other apps. To allow Adblock Fast to block in Safari:

  1. press the Home button on your iPhone or iPad,
  2. tap the Settings app,
  3. tap Safari > (under GENERAL) Content Blockers, then
  4. toggle the Adblock Fast switch on.

To unblock ads, navigate to the Adblock Fast app.

To see the effect of Adblock Fast on a particular page, you may have to clear Safari’s cache (tap Settings > Safari > Clear History and Website Data) before reloading the page.

In Chrome or Opera

Adblock Fast installs a button in your browser’s toolbar. 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 (or if you’re a masochist), you can click the button to unblock ads. Your setting will be remembered whenever you go back to the site.

Questions, possibly to be asked frequently

Who created Adblock Fast?

Adblock Fast was created and is maintained by Rocketship, an award-winning app studio based in Palo Alto and San Francisco. Our mission is to design and develop the finest mobile and web experiences, of our own and for clients.

What is Adblock Fast?

Adblock Fast is a new, faster ad blocker for desktop browsers and mobile devices.

Where is Adblock Fast’s filtering ruleset from?

Adblock Fast’s ruleset is derived from EasyList and that of Bluhell Firewall. We’re also testing an alternative ruleset that we expect to improve ad blocking yet another order of magnitude.

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

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

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 your HTTP traffic and to hide ad resources by injecting CSS into the webpages you go to.

How does Adblock Fast make money?

Adblock Fast doesn’t, nor do we intend for Adblock Fast to ever, make any money. We operate an (aforementioned) app studio that’s bootstrapped and quite profitable. Yesterday, you probably didn’t know we existed. Today, you do and, someday, perhaps you’ll be creating the next killer app and will consider hiring us. (Hmm, maybe doing good work and shipping good products ought to replace advertising!) Unlike other ad blockers, we don’t have to sell out to support our project.
