Better YouTube Watch History

Just installed it. Does NOTHING. No flag, no nothing.Nothing worthy to config too. Absolutely ****.

10\29\22 Update: This no longer works, so it has been dropped to ONE star until updated to make it work correctly with YouTube and Edge. It would help to enhance while fixing. ... ORIGINAL ... Finally. I have been in love with Firefox's Add-on "Watchmarker for Youtube" for the past few months and I HAD TO HAVE a Microsoft Edge version. Sniklaus has only made his extension available for Firefox; so it was great to find another developer supporting this. This adds a grey transparent layer over any watched videos on Youtube with text in the upper left corner saying "WATCHED". The Firefox version also greys out videos you watched previously on Youtube, so this just needs to be enhanced to do the same. Finally, this is a MUST HAVE; because Youtube has a habit of recommending videos I have already watched. This now makes it easier for me to avoid re-watching videos TWO minutes in; because we MUST stop these YouTube creators from getting credit 2, 3, 4, 5, 10, 100X from the same person, haha.

Great addon. Thank you.
