Although it blocks adds, this add-on seriously messes with some websites. Many hyperlinks on websites simply don't respond. Tried another blocker and works fine now.

Eigentlich ganz gut aber sobald ich eine Werbung blockieren will, funktioniert das nicht. Der rote Rahmen springt von groß auf klein, schwupp, habe ich alles mögliche blockiert. Auf verschiedenen Seiten wird Werbung für Games nicht blockiert. In der Suchmaschinensuche wird auch viel Interessantes blockiert

Cripplingly slow performance on my Windows machine; observable slowing on my Chromebook. The badly degraded performance on the Windows machine caused me to remove AdBlocker Ultimate, and I'll be asking for a refund.

It Blocks. It seems to block too much! Problems with Pictures at ebay. Switching off, everything works.
My Problem is, that I cannot see what exactly it is doing behing the surface. I can see "28 blocks" but not what exactly. So I'm unable to find out why sth. isn 't working.
So this is quite annoying.

Have been using this adblocker for several years. In Firefox as well as Chrome. Used to be great, but unfortunately, lately more and more Youtube ads still appear despite having this extension (latest version). Both in-video ads as well as small ad banners appearing over the background video.
Hate to see this, but I have to give 2 stars.
If it can be fixed to successfully block (almost) all youtube ads again, I would be happy to change it back to 5 stars.

Could have been good, and it works decently. Though, too many pop-up go through. Ads are a thing. But naughty pop-up are much worse, and they clearly aren't up-to-date on that subject!

On YouTube It Showed That There Was Going to be a video add and just skipped to the end of the add

for me the best till today, but 30€ year is too much

It would be good except for throwing up a popup telling me how many ads it blocked. I don't give a shit. Just block them. You know people like me have addons and settings to stop popups, what makes you think it is OK for you. Yes I can use a different ad blocker. And I will. You get two stars because you block ads. No more because you want to annoy the fuck out of me doing it.

Works great, slows down firefox to a crawl.

The latest version is much worse than the previous one. Doesn’t block all ads.

I have started using this for a week or so and I realized that it is unnecessarily blocking the live feeds of one of my sites (Sonyliv.com). I was unable to play any live shows on it.
Also, I had to trigger the "Disable adblock on this site" button every time I logged in that site.
It has also been interfering with my Hotstar site as the site stopped remembering my watched history. Uninstalling it fixed the issue.

Noticed from last update that I now can't play news video's unless I disable AdBlocker. Doesn't matter what I try in the settings it won't allow them to play. Very frustrating.

I just added this addon to Firefox and tried it out on FB and nada, blocked zero adds. Refreshed page, closed and reopened FF and the same result. Nothing. It will block elements readily but adds were still profuse.

Blocks to much causing some pages not to function correctly. It prevents panorama pic on facebook from working is one issue.

2 часа не мог зайти в банк пока не догадался откл. AdBlocker. Тоже самое на некоторых страницах. Например cont.ws . Удаляю.

Doesn't block all ads. Specifically those I meant to block because they're loud and startle me. Also throws occasional ads in your face itself.
