The only currently working tool I could find for this issue. It is P A I N F U L L Y S L O W however, any more then 500-1000 videos would take hours (based on my experience).

What a fantastic extension, a credit to the maker. I've been storing stuff that i'll get back to for years and it kept bugging me, so i thought 'blow it, start again, they are all out of date anyway.' so thousands gone in minutes. I'm glad that I googled for a solution and found this.

Thanks heaps.

I am thanking author for this expansion!

Thank you!! What a life saver

1 moove, 10 min and 1000 videos deleted. THX A LOT

It works, but is slow. I had 2,307 videos in my watch later... Not sure why it maxed out at that number, it stopped working at 1,000. Somehow it went higher.
Anyway it took about 30 minutes to delete all videos one-by-one. It REQUIRES that you leave your PC on the window, simply running a script over and over. So that's why it's slow.
Regardless it works :)
5/5. Being better is likely very, very difficult, though a selective do-not-delete list / selector would be an improvement no free extension has the feature (I have checked).

It works. It saved me from carpal tunnel syndrome, thank you very much.

Works great and very easy to use, thanks!

works good and fast

only working add-on i found. 100% recommended.

This is the only working add-on on the store right now. It removes every single video including unavailable ones. I hope the developer will never cut support for this add-on. 10/10 would recommend.
