ATO Blocker by remusao

A super minimal blocker of ads, trackers and annoyances which works out of the box:

• Blocks ads.
• Blocks tracking.
• Blocks annoyances.
• Very small memory and CPU footprint(*).
• Fast loading time(**).

This extension does not offer options to configure the behavior of the extension and is aimed at people who want a content blocker which just works out of the box. To this effect, the developer of this addon has carefully selected a set of stable and widely used filters lists, updated daily. The following lists are used by default:

• EasyList (ads)
• EasyList Cookies (annoyances)
• Peter Lowe’s Ad server list (ads and tracking)
• EasyPrivacy (tracking)
• uBlock filters (ads + tracking + annoyances)
• Fanboy annoyances

(*) The source code weighs ~70KB gzipped and ~190KB uncompressed. The raw memory usage is less than 5MB (1.7MB reported in about:performance), which is smaller than any other adblocker extension.

(**) The blocker is initialized in less than 200ms, even on cold start, which means that ads and trackers are blocked as soon as your browser starts.
