Right - I left a 3* review stating that this addon is unreliable and stops working or uninstalls itself for no good reason. I then watched it for months and edited that review to say that "yes" it definitely does that and changed it to 2* - I just uninstalled it and reinstalled and IMMEDIATELY it completely uninstalled itself! So it seems the developer can uninstall it at will. What he/she doesn't seem able to do is remove reviews. So now I will never use it again and this review goes down to 1*. If I could give it zero I would.

Es blockierte Seiten, auch als es schon deinstalliert war.

I tried this to block some of the numerous YouTube ads. It worked at first but after closing the Donate page and trying it further it really negatively impacted FireFox performance. YouTube would buffer where it never did before AdBlocker Ultimate was installed. The YouTube audio would just stop playing midway. I rebooted my PC multiple times, cleared Firefox browswer cache. Finally I just uninstalled AdBlocker Ultimate and all my problems went away except for the YouTube ads. It's not just YouTube that was impacted negatively by AdBlocker, other sites would time out or just stop working. Removing AdBlocker solved the problems.

YouTube is injecting so many ads now it's getting irritating like the old popup browser ads we had in the early 2000's. I guess they want to irritate viewers to pay $9.99 a month but everyone wants $10-$15 month for content, Netflix, Hulu, YouTube, CBS, Disney, ESPN, Amazon...etc. I already pay for 3 services pr/mo + Internet.

Anyway, AdBlocker Ultimate really bogged FireFox down and who knows what information it collected along the way. Not recommened.

There's no way to see what it has blocked. According to the developer, "a filtering log is only available in our desktop ad blocker only". Also, there is no way to whitelist only part of a website (for example, to whitelist "https://www.example.org/admin/" but filter the rest of the site normally).

your adblocker is shit and doesn't work

bad, very bad!

not free. hounding me to pay and blocking pages with their solicitation! Pd for Ultimate, worst mistake. Can't block entire ads, only sections. Labor intensive and almost every page still has ads in it DO NOT PURCHASE OR USE

Doesn't filter youtube ads.

Worst adblocker i tried so far. Every single ad from youtube interrupts the content i´m trying to watch as if there where nothing preventing it.
Absolute 0.

bloqueo los primeros dias, despues no hizo nada mas..

Doesn't block YT ads, inappropriate "Chat with singles" type of ads, pop-ups, clickable elements. Just useless.

Doesn't work on Twitch.tv

What's the point of having an adblocker to stop annoying pop-ups when the same adblocker splashes its own adverts across YouTube videos at crital moments while watching.
Clearly a case of marketing department intervening with engineering again...

Did not block Youtube ads, did not block popups and was missing many ads. I hate this ad blocker.

This Add-onns is so buggy it slows my internet connection so bad and yeah it slows my mozilla too and when i remove it. It's good now it is not slow now please fix this bug or remove it

I am having problems with other programs refusing to work until ad blocker is removed; however, I am unable to remove it.

Free trial garbage. Keep using better and free alternatives like uBlock Origin and don't bother with these knock offs.

Didn't block ads.... at all

It worked fine, but I didn't realize it was a trial for a fee-based service. I quit the app but daily get pop-ups from it and want it to stop.
