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.
