Guys, just delete it and install again, worked for me here. Greets

5 star. Helps a lot keeping the add away.

same here the update caused all web pages i loaded to not load or function correctly however i am not going to rate it less stars simply because of a bug that im sure they will fix maybe if they do not fix it i might but for now i just chose see all versions under version history in the more information panel below and installed previous version then disabled auto update until there is another update.and ty developers for keeping my privacy safer i appreciate your hard work and time.

works fine

I loved it! works supper well.
Just that google lastly is playing dirty and working bad when it detects this ad blocker.

I hope there is a way to the websites cannot detect the ad blocker.

Doesn't work with safe filter on. You can disable it in Settings ->Filters -> Security -> Click on switch / Не работает с включенным фильтром на безопасность. Отключается в настройках -> Фильтры -> Безопасность -> Переключаете в выключенное состояние

Great adblocker, also great for disabling distracting elements! Unfortunately when I woke up today, a lot of sites had issues, from YouTube, to Google, to DuckDuckGo, to WhatsApp and more. They all worked again after disabling this extension. Hopefully the error gets rolled back or fixed soon :) (Thank you devs for all the ads you've saved me from so far!)

Hope this helps anyone who sees it. Many sites stopped working after the 4 Aug update, but I managed to get them working again after going into the extension settings, Filters tab, and turning off the Security filter. The Ad filter continues to work fine.

Youtube blocks playback now, if you have it activated on their site, uninstalling, I'll have to look for alternative

As others have said, whatever was done in the recent update has messed up everything. I can't even view emails or use Google properly with the add-on enabled. Please fix this! It used to be great :(

*Edit* The fix for this issue seems to be removing then re-adding the extension. Everything is working as it should again so I changed my review to 5 stars as the problem seems to have been caused by the recent Firefox update and is not the developer's fault.
