uBlock Origin's GUI is (by far!) not as clear and instructing as the former uMatrix's one. So I don't feel being as much "in control" of what a web page is trying to get from my web browser... As a consequence, my trust in uBlock Origin suffers.

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!

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.
