AVOID these guys. Notice they are AdBlockER with "ER", not AdBlock!! From some shady folks in Bulgaria (the real AdBlock is German I believe).

It's a Free trial, but on expiration it continues to add a floating shield icon to many Firefox pages at bottom right, which prompts you to upgrade and pay.

Remove it with Firefox menu, remove it with Control Panel programs, it's still there. Directory "C:\Program Files\AdBlocker Ultimate" cannot be deleted, because there is a process, visible in TaskManager. Reboot the PC. Process gone, directory can be renamed.

But still, when I open my email client (fastmail) in Firefox, it still hangs for a long internet-timeout, saying "Connecting to self.adblockultimate.net"

Не працює перманентно. Постійно приходиться повторювати блокування вручну. Проходить деякий час і знову все що блокував повертається

Slows down Firefox a lot. Firefox uses lots of CPU and just hangs. After I disabled this no performance issues whatsoever.

AdBlocker Ultimate no longer works with YouTube.

No longer works with multiple sites

Doesn't block all. useless!

Absolutely DOES NOT work on PCH.com All I see are ads, ads and more ads... totally does not work on Firefox. Does NOT "Compleetely remove ALL ads."

Got this extension to block ads, then starts showing me very annoying pop ups about the extension. :( Uninstalled.

i do not want this.someone also is charging me for my android phone please stop charging me

Your ad blocker is now blocking Amazon Prime Videos from working. It has been going on for a month or two. All I do is remove AdBlocker Ultimate and my videos will run fine. Everything else is good. Please fix this. Using Firefox 120.0.1 64 bit and Win10

It's impossible, but somehow all those people rated it a 5, when this add-on blocks a lot of wanted site functionality. A few times i restarted Firefox or Windows bc i forgot to disable it when something didn't work on a site No more, it happened in Chrome with its version of this add-on loaded and this time I've just gotta remove this dysfunctional add-on.

Does not work in YouTube :(

Absolute garbage. This is one of those adblockers that takes money from google and disables addblocking on certain types of ads. If you are running multiple ad blockers it will override them and show the google pushed ads on websites. Any adblocker that thinks certain ads are okay are compromised and garbage. Just use something else instead.

Efficace

Have been using this adblocker for a few weeks now. It lets ads through constantly on Youtube. I've checked and there are no updates. Does the developer make money allowing certain ads through? Am going right now to find and try some other adblockers as I'm sick of being interrupted by ads with scumbag scammers trying to sell me crap I don't want.

the newest update of 16 november 2023, since this update my pc uses 99.98% of the 16gb of ram, it ramps up till it uses just about all ram, as soon as you disable AdBlocker Ultimate in firefox/mozilla, it instantly drops off and the ram sits back to its normal amount usage between 2 to 4gb, i have had this same problem by the same adblocker twice before, not good when it hogs the ram and nothing has been done to fix it
