This addon has caused nothing but problems for me across many websites. Adobe's website doesn't show prices, a photo downloader wouldn't retrieve the file, a Microsoft Sharepoint site wouldn't load any of the files, and other problems with Samsung, some forums and even Google. All solved by disabling the addon. I'm doing SO MUCH disabling that it's not even worth having it. I've never had these problems with AdBlock Plus. UGH!!!

EDIT: Also just found out it was this plugin responsible for making Paypal give me errors where it was impossible to pay. Worked as soon as I disabled this. This is with no custom filters. Madness. Definitely removing now.

Crashes mobile Firefox every time, so I had to remove it.

Basically no difference someone recommended ublock to me but it is useless I'm going to go back to what I had before.

Still getting ads with this.

Через некоторое время работы поле последнего успешного запуска браузера блокирует интернет вообще. Помогает только удаление и переустановка дополнения

This extension was great until it blocked REST requests that simply had *adverts* in their name and not saying anything about it in the console.

eating too much memory..! checked in firefox

I love this extension on my PC, but here on Firefox mobile it seems to have a problem where it consistently causes pages to fail loading. Only thing that fixes it is restarting the browser and it happens often enough that it's a real hassle.

Horrid app. What did you people do? Takes literally 50 to 60 seconds just to open the firefox browser to google.com and every web site as well. I haven't seen a computer run this slow since dial up 1998. Oh and Peter Lowe’s Ad server list blocks google shopping and ebay???WTH!!!

Now blocks timeline of multiple columns in Tweetdeck including Home and User. Same with Nano Blocker

uBlock on ff66.0.5 started to block everything. not loading any webpage anymore. i had to switch it off.

Blocks infowars players. You have to shut off this blocker to watch infowars players
