After years of successful use, for last few weeks this extension is broken, even after several reinstalls. Sad to look for an alternative...

No longer working on Facebook with Firefox browser!

Used to be great now pop up ads come through without any issue. Went with a new blocker and the pop ups stopped.

Used to be really good, now it blocks so much content that most websites simply don't work. Use uBlock instead.

Adblocker Ultimate caused a problem with my screen and interfered with Google Chrome. When I uninstalled it the problem went away. I thought the graphics card in my computer was defective and I'd need to buy a new computer, but it was Adblocker Ultimate.

Stopped most pages from loading CSS and JS completely, breaking basically every website until I figured out what to disable.

Literally causes most web pages to stop loading any content whatsoever. Various sites became entirely unusable and never loaded with this extension installed. 0 stars. In addition, seems to totally strip CSS styling from many pages, leaving them completely unorganized & unthemed.

I have installed this ad blocker a few times off and on. Today will be the last time! It stops You Tube from playing and all other video you might play like movies and such. I just re installed it 2 days ago and utterly disappointed in it. I have used this for many years and I no longer trust it.

Getting youtube adverts again. Still getting youtube adverts again!!

Videos no longer play on YouTube... Just buffering.

For the last 4 hours the ad blocker is interfering with any google site you tube keeps buffering , google drive cant open my folder etc maybe something is disrupting it, as soon a s i turned it off its working. kindy check and make any updates to the add on

No longer working on YouTube using Firefox on MacOSX - Looking forward to it being fixed.

No longer works on Youtube, Firefox latest version.

For many years this ad blocker worked well blocking YouTube ads but no longer. Now the green line still shows where the ad is but the ad still plays so I have to scroll ahead to get past it. I installed another ad blocker, sorry AdBlocker Ultimate.

ublock better

It still will not block ads on youtube

I fell asleep with a youtube video on, when I woke up adblock had somehow managed to block the entire actual video, and there seems to be no way of resetting rules on a given website, so the extension has now made youtube useless.

the previous version was much easier to use. Menu options for all choices

полный скам - из-за него браузер частенько подвисает при загрузке страниц (причем как то хаотично рандомно). Причем подвисает именно загрузка страниц, а еще и других расширений, при этом сам браузер работает. Наверно периодически перегружает браузер или вызывает какие то внутренние ошибки загрузки, из-за чего ни сайты ни расширения не откликаются какое то время. Вообщем, если с таким столкнетесь, лучше удалите его и поставьте другой блокировщик (я к сожалению не сразу понял что это из-за него и долго с этим мучался). У юблока например таких проблем нет. А я теперь вообще не доверяю этим "адблокам", ибо не с первым уже проблемы.
+явная накрутка голосов (в сравнении с другими расширениями это заметно)

full of scam - because of it, the browser often freezes when loading pages (and somehow randomly). Moreover, it is the loading of pages that freezes, as well as other extensions, while the browser itself is working. It probably periodically overloads the browser or causes some internal loading errors, which is why neither sites nor extensions respond for a while. In general, if you encounter this, it's better to delete it and install another blocker (unfortunately, I didn't immediately realize that it was because of him and I suffered with it for a long time). For example, the ublock does not have such problems. And now I don't trust these "adblocks" at all, because there are already problems with the first one.
+obvious vote fraud (this is noticeable in comparison with other extensions)
