Excellent - wouldn't be without it.
A must for watching Youtube videos.

after updating Firefox AdBlocker could not to block advertising

Works as advertised, no complaints.

Appeared "broken" after a recent update, but this solved it: Click AdBlocker icon on Firefox header, click on "Settings", and click the Refresh icon (top right corner).

AdBlocker Ultimate worked extremely well on FAcebook (PC, Windows 7, Firefox browser) for a very long time. I've recommend it all over and have been well pleased with this Firefox plugin. But, all of a sudden, NO ads are blocked and FB now floods my feed with ads. I've tried blocking elements, but that is an eternal job with no end in sight; I've tried uninstalling and reinstalling the plugin....nothing works. I could use some help with this, please!

AdBlocker Ultimates power levels are too high right now. The anonymous tag being sent is breaking nearly everything on the browser. Maybe a spoofing script to patch the tag will be necessary. Download this blocker, just dont activate it until the bug has been fixed

Worked great till this afternoon, now it's blocking the ability to load pages

Worked great until today. Can no longer connect to any site. Please fix.

ウェブサイトのUIを壊しています。
これを現在一時的に使用を中止しました。 開発者は、更新によってエラーを修正する必要があります。
It's breaking the UI of the website.
We have temporarily disabled this for now, and the developer should fix the error via an update.

Up until a week ago, it worked fine. Now it completely blocks some sites and I have to turn it off. You've got a bug somewhere.

I hope you fix it

Bricked my browser

Randomly broke every website

Worked great until today. Most sites won't load anymore, it basically broke the Internet.

~Silent updated killed this extension.~

Rules have been fixed since, functionality restored.

Until today this was working fine.. Now the interwebs are all broken :(

this just completely broke my browsing, everything just completely stripped down to unusability. it's been perfect until today.

Works amazing! Until it doesn't. For some reason, I and thousands of others have witnessed the app somehow destroy the internet. Hopefully there will be a fix soon.

Extension seems to have gone off-rails, it's been blocking all requests breaking almost all websites for me. No stylesheets, no js requests is being served because it blocks everything.
