The best I've found.

Love not having those annoying ads in my email and sites I visit. The only annoying thing now is the sites say they can't make money with ad blockers so please allow ads. I just click close and continue on my way. Close to, if not, the best add on I have.

Basta installarlo ed i settaggi di base eliminano il 99% degli inserti pubblicitari nei siti.

nice ad-blocking powarrrrrrrrr

I've been using this software for 3 years now & I'm totally satisfied with it. No more untimely ad spamming. Very simple of use, you keep control on what shows or not. I will keep on using it & advise it to people who want to get rid of overwhelming advertising on internet.

Delivers exactly what I need, its free, it doesn't slow FFox down (not that I notice anyway) and it isn't complicated to use, it just works... what more could you ask for... Brilliant

efficient

Not bad but still getting an ad or two on some sites that have video content.

Ad-blocker Ultimate keeps my sanity when using YouTube or Facebook.

Any program which helps reduce JUNK being loaded onto my computer is okay by me.

Well, it's easy to use and it's working properly.

Ad blocker is great and functions quietly in the background, only problem now is that a lot of websites 'detect' your ad-blocker and ask you to turn it off, mostly not a problem apart form the ones that won't let you access their www whilst it is turned on! Not sure what the answer to that is other than boycotting their sites!

Excellent

I donated because the web would be almost unusable if they stopped development on this plugin.

I have been using AdBlocker for several years. Its function can't be seen, however, it does work well, I think.

Excellent Add-on for blocking all those annoying adds...It's a must for Firefox.

I have been using Ad Blocker Ultimate for some time and am completely satisfied. Very rarely does something creep through. It is wonderful to have no distractions. With a cognitive processing difficulty, this is essential. Thank you.

It is refreshing to not have to wade through all the useless ads that were on every site I went to. Now I can breeze through a website and get the information I need and not be distracted or annoyed. Great Add-on!

Great utility, however, with their latest upgrade whenever I click on the Firefox Home Button the current displayed webpage freezes and my browser won't return to my homepage which is "about:blank".

I disabled the few add-ons that I use and re-enabled them one at a time until I found the culprit - Adblocker Ultimate. I then uninstalled then reinstalled it but to no avail - same issue.

All of my programs and utilities are up-to-date. My platform is Windows 10 Creators and my browser is Firefox 55.0.2.

Unfortunately, I have had to disable this very good utility until that bug is fixed as I use the home button constantly with a number of tabs opened at once.

Other than that, I have no other issue with this great ad-blocking utility and have used it for a very long time.

Thanks

Love AdBlocker because it speeds up my browsing. I don't get the ads anymore which cause my machine to crash as often. Thanks for a great product!

I have had ZERO ads pop up since installing Adblocker Ultimate. It works very well: I haven't noticed any bugs or slow performance issues. I definitely recommend it!

works like a charm

The best app! Never shows up with ads or something. It Just Works!
