First day using it and it makes its own popups asking for ratings, I dont want to see any popups, annoy me for a rating and you always get 1 star

When I disabled adblocker on certain websites, it would not stop those sites from asking me to disable adblocker to view them. I added them to the whitelist and that did not solve the problem. I deleted adblocker Ultimate and even that did not solve the problem. I have many websites I can't use anymore because I keep being told I have to disable adblocker. Deleting this extension did not solve the problems that were created when I installed it!

It popped up a window wanting me to purchase the ultimate variation...and it wouldn't let me get past the pop-up, it kept blocking the game i was trying to play. I HATE pushy apps!

This extension doesn't block any ads on firefox browser

This has yet to block a single ad on a single website I've visited

Вообще не фильтрует

Since deluxe rollout installation today (2/25) this has blocked all audio streams repeatedly, despite being turned off. This did not occur in prior editions.

not blocked Youtube adds

Blocks too many things. Somehow several sites would not allow me to login, although they were fine and are legit. Some sites would not display their content - they are legit. I will go back to the old stuff that worked for years. Sorry.

I am an equestrian. The language used in our world does not fit your program. When trying to order a headstall from a reputable website, your program automatically refused access. I had to uninstall the program to continue. Sorry to see you go but riding and providing the proper equipment for my horse is very important to me.

There's this stupid adblock icon on the bottom right corner of my screen that is trying to make me buy something and it won't go away no matter what browser i'm on even with the extension uninstalled it's still there, i contacted support but i haven't heard anything back really bothersome wish i didn't install this cause it won't go away no matter what i do

No good still show youtube ads and facebook ads

my computer has never been the same. Is it causing problems?

Doesn't do anything to stop youtube ads.

Clam said it contains a coinminer: adblockultimate@adblockultimate.net.xpi Js.Coinminer.Generic-7132237-0

Update: This is still a problem.

Breaks websites and keeps interfering with login pages. Have to constantly disable on sites just to be able to log in and then re-enable the add-on on the site.

Cuidado es un fraude, si vas a realizar un pago en mi caso a mercadopago mejor eliminen esta extension, crea paginas falsas de mercadopago para que deposites en su cuenta y no en la tuya. Me robaron mi dinero. :´(

YouTube no longer works in Firefox. As soon as I disable this add-on it works. Boo!

Just installed it. Didn't work on the first site I visisted
https://www.javatpoint.com/fault-tolerance-with-hystrix. Didn't work. So tried www.cnn.com. Same deal.
