This works exceptionally well to remove all the distractions and annoyingly excessive 'fake news' videos in the sidebar.
This is THE BEST YT distraction blocker so far. The others eventually 'break' YT functionality completely.
However this one might use your computer as a proxy doing who knows what to who knows whom?? The TOS is too broad for my liking. Make sure you understand what you are agreeing to before installing this addon.
