It runs well, and I haven't seen ads.

Love this adblocker! It keeps break-through, intrusive ads, cookies, and malware away from me, and has a really small footprint in the browser. Too many sites have gotten so bad about ads and cookies that content can't be accessed at all without a lot of pain. Add Blocker Ultimate does not block indiscriminately, however - it can be customized and tailored to fit your needs while allowing relevant content through. My favorite kind of browser add-on!

Fabulous 'addon'! Does what it advertises and best of all it's FREE! Can't ask for much more than that. Thank you.
