Ads? What ads? I never have to worry about aggravating ads as long as I have AdBlocker Ultimate!

So far it has done a great job. Do get a few popup "ad block being used" warnings but haven't been blocked from reading content. Haven't checked to see if it hogs memory or fails to release memory when not needed.

I would like to see what has been blocked on a site and have an option to unblock temporarily. Do recommend this extension.

One of the best AdBlocker out there. It doesn't seem to slow down Firefox!
