Just what I was looking for. I use this addon in combination with some scripts, because the scripts don't seem to work 100% of the time.

2. https://greasyfork.org/en/scripts/433408-youtube-url-tracker-remover
However your addon doesn't seem to fix instagram, facebook url tracking!

https://l.facebook.com/l.php?u=
This is why I have blocked these sites with 0.0.0.0 with uBlockOrigin ... this way I can manually copy the links without the tracking.
