AdBlocker Ultimate is a free extension that blocks ads and malicious domains known to spread malware; it also disables sneaky tracking. We have extensive filters that filter against annoying display and video ads (including YouTube).
Unlike other ad blockers, we do not have “acceptable ads” or an advertiser whitelist (i.e. certain advertisers pay to bypass ad filters). Blocking ads has the added benefit of speeding up browsing because filtering out ads reduces CPU and memory usage.
AdBlocker Ultimate allows you to easily accept ads from websites you choose, in cases where you want to give advertising credit to certain trusted websites.
