Unfortunately seems to have an issue with memory leaks, since installing the add-on firefox routinely reaches 5gb+ RAM usage after a few hours, even without actively using it or having a video open.. initially noticed it after checking task manager following performance issues only to see firefox using over 20gb of RAM

Otherwise a great add-on, making youtube infinitely more usable, while being quite customizable.
Only an option to fully collapse the sidebar in general, not just on the homepage would be nice
