very good

Best adblocker on the Internet! Although may cause some pages not to load (or partially), may be a sign to stay away from these.

No rules to setup before usage, although if desired, can block (blacklist) sites or allow (whitelist) others. The setting can be found by clicking onto the AdBlocker Ultimate icon.

On a scale of 1-5, a solid 5 Star security extension for any Firefox user to have. There's also installers for other popular browsers, there may be a cost if not natively offered with browser.

EDIT: 2 years after my initial review, everything is still great, highly recommended extension & 100% satisfied!!!

Works seamlessly in the background and is very efficient - totally blocks all advertisements. Highly recommended!

Best ever ad blocker. Youtube is more fun to watch.

Very useful!!!

best adblocker there is!!!!!!!!!!!!!!!!!

Doesn't filter youtube ads.

Once installed and setup you can forget and carry on .. youll notice how quiet it becomes as it stops ads flooding your system just as it should be ... WELL DONE
