web browsing is a pleasure again! stops so many annoying pop-ups! feel like it's the late 90's again, makes for a very nice web experience. must have add-on!

I am very happy with AdBlocker Ultimate: it stops all kinds of ads from different websites, and it's super easy to Enable/Disable it when you want to - just click a button. I've been using the extension for more than an year now and no glitches so far! Highly recommended 5/5

Better than ever :)

Its so nice not having Ad's constantly flashing and cluttering the screen up. Ad Blocker Ultimate is quite simply the Must Have extension for anyone using FireFox

well happy saves loads of time

I'm not really sure what to say here. Does it block ads? Yes, pretty much all of them. Does it stop popups? Well, I haven't had any since installing it, but then Firefox does a pretty decent job all on its own, so I'm not sure who gets the credit. Is it easy to use? Yup - clean and informative UI that lends itself to an excellent UX. Is it lightweight? Absolutely.

So, yeah - it's a great adblocker. Does what it says on the tin.
