All of a sudden this plugin is breaking websites (Google, Twitter, YouTube, etc.).

With 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.

Its been breaking every site since the update idk whats going on

Locks Youtube 100 % from 23th Dec 2025

As 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

Burned method, also just use ublock

It breaks almost every site since 20.11.2025.

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.

The 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.

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.
