Adguard just dropped the ball. They now limit the number of filters you can use. uBlock is good but not the most effective in blocking annoyances and stubborn cookie notifications.

Ghostery is the next best option or Brave but I have some doubts it won't be forced to move to MV3. Otherwise, the trend is to move toward a hybrid/Fork Chrome browser or a FireFox clone. Regular FF is too slow, heavy on CPU use, and writes more in the background than other browsers.

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

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.
