Using this since a while, but it stopped working in my master YouTube browser. Trying in a different clean browser, made it work again, however I don't see a reason, why it stopped working in the original one.

One of my go-to addons for a long time now. It works perfectly.

This works perfectly. I tend to close Youtube accidentally despite having a video playing in the background. When returning to the video, it has an outdated timestamp bookmark from one of the last sessions, that doesn't seem to want to update.

This, handles it completely. Didnt even need to restart. I see Youtube try to jump to its incorrect bookmark, but right away this kicks in and takes me back to the second I was watching!

Thank you!
