When it works, it works. Unfortunately it's missing crucial features, like

- undoing latest blocking action.
- listing ALL manually added filters (only shows a few dozen and then the list cuts off).
- search function for "Add Your Own Filters" in order to remove an item from the list you accidentally blocked, which means you need to completely reset the addon and start from the very beginning.
- keeps redownloading foreign language filters that I've disabled AND deleted. It's annoying.
- the Adblocker menu stays open when you click "Block Element" (whereas it should disappear automatically), and blocking box is often hindered by the annoying Selection Mode popup.

I've reported these before to the support email but was ignored. Doesn't really encourage me to donate when maker is oblivious to feedback.

It seems to make my laptop somewhat slower. I guess that is a small price to pay to not see the adds.

No bloquea los anuncios de openload.

Good ad blocker except it gives you pop-ups advertising itself. Block those ads too!

Great add on
Dios Enterprises

It blocks ads and is unobtrusive, but when enabled, there is a very noticeable and distracting flicker when loading different views in a website...

slooow! slower than adblock plus or ublock origin.

No whitelisting tube channels.... omg

Eliminates probably 85% of ads. THat's great. It also blasted me with a huge popup asking for a review. A subtle email would have garnered them a much better rating.

super tool

まあまあ

The interface of Adblocker Ultimate has changed with the latest update. Clicking on the button in a Firefox window gives some options, that don't make sense and some don't work. Also an ABPVN list has been added to the default filter list with no explanation as to what it is. This together with the sudden change of layout of the extension has forced me to remove it. What is going on here ?

slowing youtube.

It did not remove Yahoo Mail ad banner! Would have donated otherwise.

For some time I could not understand why the sites are not loaded, all the tabs stop working at once, as if the Internet was disconnected, this does not happen often, but as hangs and a few minutes have to wait, by exception found that the blocker is to blame...

Repeatedly fails to block some ads even when a custom filter has been added and even when ads have an obvious "advert" tag on them in Norwegian which should make them easy to filter. So it only partly works.

This is great but at the same time shit. Whitelisted sites still have the blocker working on them. I have one site I use that it's blocking more than just the ads. The blockers are adding themselves automatically and the main English one won't disable. No matter how many time I shut it off and delete, it just keeps coming back within seconds.

I have a couple sites that have no ads whatsoever on them, even a private forum, but it's still insisting it's blocking something but there's absolutely no loss in functionality.

So this gets a 2. I'm not confident this is a legit working app the way we are led to believe it is.

It blocks youtube movies on websites and hides Google captcha so you are unable to log in at sites using the captcha

Good browser overall, but customer-testing-before-launch seems to have been disregarded when new features are introduced. I have had to spend a lot of time figuring out what & why things have changed on recent updates. That is a lot of wasted effort when thinmgs get busy in life.

Doesn't work on Mail.ru

blocks too much on sites with exoclick anti-adblock protection.
