- Rated 1 out of 5by T0X1N, 12 hours agoAll of a sudden this plugin is breaking websites (Google, Twitter, YouTube, etc.).
- Rated 1 out of 5by Firefox user 19652499, 7 days agoWith the update from December 28, 2025, at 2:02 p.m., I can no longer access my router even though it is on the whitelist and should therefore be available. The previous version had taken this into account.
Since this problem exists, this add-on has become worthless to me and will be uninstalled.

Mit dem Update vom 28. Dezember 2025 um 14:02 kann ich nicht mehr auf meinen Router zugreifen obwohl dieser auf der Freigabeliste steht und somit eigendlich verfügbar sein sollte. Die Version davor hatte dies berücksichtigt.
Da dieses Problem besteht ist für mich dieses Addon für mich wertlos geworden und wird deistalliert. - Rated 1 out of 5by Firefox user 15318144, 8 days agoIts been breaking every site since the update idk whats going on
- Rated 1 out of 5by XuluWarrior, 15 days agoAs other people have reported, the extension has become worse than useless. It's blocking core functionality of website, happily reporting how great it is.
e.g. on one (fully legitimate) share trading website it, for reasons unknown, is blocking deal-now-button.jpg and all the chart data.
No way to control it.
No way to even see what it is blocking without looking in the Network debugger.
Time for a replacement - Rated 1 out of 5by Kliman, 18 days ago
- Rated 1 out of 5by Max, 2 months agoAfter years of successful use, for last few weeks this extension is broken, even after several reinstalls. Sad to look for an alternative...
- Rated 1 out of 5by Firefox user 17832515, 2 months agoNo longer working on Facebook with Firefox browser!
- Rated 1 out of 5by Jim, 3 months agoUsed to be great now pop up ads come through without any issue. Went with a new blocker and the pop ups stopped.
- Rated 1 out of 5by WillsterJohnson, 3 months agoUsed to be really good, now it blocks so much content that most websites simply don't work. Use uBlock instead.
- Rated 1 out of 5by Alan_Wells, 3 months agoAdblocker 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.
- Rated 1 out of 5by phantoids, 4 months agoStopped most pages from loading CSS and JS completely, breaking basically every website until I figured out what to disable.
- Rated 1 out of 5by Novimatrem, 4 months agoLiterally 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.
- Rated 1 out of 5by Firefox user 13952389, 4 months agoThe team behind adblocker do not operate any type of forum for support or state data so it is impossible to tell what is really going on.
Again it has just failed, which pages now breaking and broken content being show. Without any status info it is impossible to tell if their core systems are under attack or just overloaded.
Being open about issues would likely help the situation as at least their users would understand what is going on. - Rated 1 out of 5by MG, 4 months agoI 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.
