Sorry but I'm not writing a review, pushed the button by mistake...

Good, but functionality with Youtube is spotty atm and the zapper function is pretty much only good for getting something out of your sight immediately for the duration that it's on screen.

right now ublock isnt working fully on youtube one work around is to delete cookie and site data and closing and re-opening firefox, it should prevent youtube from detecting that you are using an addblock

So far so good - except tired of seeing it pop under my other open tabs. May dump and find something else

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.
