Every time i open Firefox I get a page telling me this addon has been installed and my block list has been deleted.

хорош !

There are no acceptable ads. Don't waste your time with ABP. Install another adblocker.

Adblock Plus used to be nicely functional ad blocker but, Google or another advertising company must have paid them a ransom or something else is going on behind the curtains because it no longer works. A new option has been added: allow acceptable ads. It is not possible to keep it disabled. I disable it and next time I restart Firefox, it is enabled again. On another note, these so called 'acceptable ads' are those Everyone is running away from. It's like not having an ad blocker at all. Two stars only because it was really functional in the past but as of now, you may call it anything like a chicken or toasted bread but not an ad blocker.

ВСЕ супер! Только почему-то часто на дефолтные настройки слетает и удаляет персональные фильтры

Perfect, but one only thing, some times the adblokP Does not block all ads in certain website!

I have been using ad block plus for eleven years, not switching back, ever
