easy and cool

Obviously not your fault, but just letting people know, there are ads on YouTube that get around this right now so wait for a more recent update.

The only way one can see what scripts are being blocked are by using the 'Logger'. When I eventually found it (a link to it is found in the support menu) it erroneously reported nothing. The UI of uBlock Origin needs a redesign. Unlikely - the developer has a tendency to be recalcitrant when offered criticism, which I totally understand.

Not bad. But reacts too slow on Youtube malicious ads and their pathetic attempts to fight adblockers. In Brave browser everything works in instant, but uBlock takes several days or even weeks to apply corresponding update. I hope uBlock will put more efforts into fighting youtube. Fuck google! Freedom to the internet!

Manifest V2の規格をFirefox側(派生ブラウザも含む)が、維持、Chromeと違うところを続けてくれれば、uBlock OriginとFirefoxは、使用する価値がある！
uBlock Originの評価は、４としたが、これからの動向により５評価にしても良い！

does not work on YouTube anymore...no recent updates...has YouTube won the "war" ?

Great and would be 5 stars if my choices were backed up to the cloud. If you reinstall FF you lose everything and have to start again.
