I don’t have a YouTube login on purpose. After having had issues with some random videos asking me to login to confirm my age (no porn or anything, seems to be random harrasment), I now get “log in to prove that you are not a bot” (rough translation).
Have you tried Newpipe? It’s on F-droid.
That would be for Android. No, I prefer watching videos on a screen. This happened on Firefox on Linux.
Free Tube is an option
Installed it, tried it, got an error message that was gone quickly. I’m now searching for an error log, but so far no success.
Youtube just changed their ad blocker again, so freetube/invidious will be down for a day or two
I’ve seen short upheavels caused by youtubes greed these days when they complained that they did not like adblockers, but at least the video restarted after a short hiccup. This seems different. No, this is different, I just checked.
Pipepipe is basically Newpipe with sponsorblock added. I recommend it over Newpipe/Tubular.
