Pretty Good Rated 5 out of 5 stars
AdvertBan doesn't have all the features of Ghostery & Adblock Plus combined but it does do one thing that they don't very well which is not cause crazy memory leaks in Firefox ballooning memory usage to huge amounts over long browsing sessions, yes some of these leaks are Firefox itself but Ghostery and Adblock Plus are also responsible (even in the latest Aurora 8.x builds that fix some of the Firefox leaks).
The UI is pretty simple to use and it is faster but doesn't offer a whole lot of control over what you block & can whitelist like any https site for instance.
If your tired of memory leaks or websites catching on to Adblock Plus (giving you annoying warnings) then AdvertBan is a credible alternative.
Thanks for fair review :)
