Conflicts with VKontakte, blocks useful information along with advertising.

Конфликтует с вконтакте, блокирует вместе с рекламой и полезную информацию.

Why would an ad blocker require access to "my data across ALL websites"? Beats me. If that changes, I might reconsider. Peace.

Has not blocked advertising on YouTube for about 6 days. On the contrary, it automatically switches on that advertising is allowed on YT.Although I have clearly set to block them

Don't block ads on YouTube any more. Just add feature which you can't disable. Turn it on without warning or something like that. Sold out to Google. Ok, find a new one.

Doesnt block ads on YouTube and removes the button to skip those ads.

Non-functional bullshit instead of blocking YOUTUBE VIDEOS on Macbook you get some crappy spam about "new" products

C'est la 6eme fois que je tente de télécharger ce logiciel mais ça ne fonctionne pas!

So so so frustrating that AdBlock comes with spam these days. Every day, Adblock opens a New Tab requesting that I pay to upgrade to "premium Adblock"...whatever that nonsense is. This behavior only began roughly 1-2 years ago, when Adblock started going downhill. The straw that broke the camel's back tho was that Adblock recently decided to hide the "Block something on this page" button—the only feature that I ever really valued. So, reader, do yourself a favor: skip Adblock & just stick with **uBlock Origin**... it's free, zero spam, & vastly better performance.

First thing that happens is that you are presented with a page that asks you for money. Where in this FF posting for this add on say that you must pay for it? Not interested, thanks. Bye

The ad blocker has intrusive pop-ups just like the things it's designed to protect you from now.
They disguise them as "update" notifications but they are pushing updates every week and if you have the extension on multiple devices it will take over whatever tab you have open and show you that it's updated for the 5th time this month on every single device and conveniently also have an option to donate money.
The annoyance quickly builds up. After being interrupted and having to close a good 20-30 pop ups across all my devices a month, I'm done.
