i have been using firefox+uBlock Origin and until last week i only had to log out, clear all app data from brwoser and as precaution flush ubo cache, once a day and that worked. but since couple of days ago i have not had to log out and it works just like always. either ubo got some new filter or youtube reverted some intrusive changes.

i have also installed freetube which works great except recommendations because you are not logged into youtube so it lacks history.
