Adblock Plus

As of this morning, YouTube is completely unviewable when using ABP. The page simply shows "grey boxes" where the videos would normally appear.

It's definitely cased by ABP, as disabling it on that domain fixes the issue. It definitely wasn't introduced by a Firefox update, as Firefox itself has not been updated (I have auto-updates explicitly blocked by means of policies.json, so I'm 100% certain it didn't update itself without my knowing). After the issue appeared, I tried manually updating Firefox to see if it resolved the issue, but it did not.

It seems YouTube is no longer viewable at all, unless I disable ABP.

Any idea why this would've suddenly changed - and more importantly, how to fix it?

reinstall abp?
i use yourtube on last ff and last abp
all work normally

I have nearby same problem since yesterday AdBlock Plus dont work at YouTube sites. Are there any official problems knowned?
(Restart, on/of site tryed). But for me the vidoes comes but with comercials! (Have never remembert that come soooooo much comercials at YT, horrible i cant whats anything).

Is there a generell problem (maybe YT have chance anything to block AdBlockPlus or so?) or is it a problem from my pc side and for all other people all is fine?

Thx
