You might have noticed that even on Firefox (depending on your lists) YouTube may detect uBlock Origin on Firefox now
There's already a workaround (found, again, here), but I figured I would use this opportunity to tell people that projects like Piped and Invidious exist, which both allow you to watch YouTube without loading their ads, with improved Privacy and (in the case of Piped) even Geoblocking-Circumvention and SponsorBlock out of the box.
They're both great tools, and using something like LibRedirect you can even automatically go to Piped or Invidious when clicking/opening a YouTube link (and more).
Both don't load ads, but unless changed in the settings Individous may still make connections to Google/YouTube to load the video(s) themselves.
Bit of a shameless plug for these projects, but I figured this is a really good time to show these projects as I often see people asking what they are in threads on here
Both take resolutions and streams directly from YouTube, my guess is that it may vary a bit depending on the settings the instance host set.
