Rated 4 out of 5 stars

I think no one out there can be browsing the web without Adblock Plus or No-Script: these are my two primary addons for Firefox; I don't even visit Google without having them both installed.

I suggest: adding a search box to the Preferences window (just like in the Blockable Items window), to allow search and filtering from the Blocking Rules list.

This review is for a previous version of the add-on (1.1.2).
