I don't get it. It doesn't say anywhere what it's going to do. It has a button that says start cleaning, but it doesn't say what cleaning does, does it delete them? Which ones does it leave? How do I leave recently added ones? How do I move others to a different playlist? Nothing is explained.

Work as per its name. Brilliant extension. I have used some other extensions also but they break process if you switch to other work, but it continue to do its task.
I request the developer to add a option of removing Liked videos also.

Does work, but says it can't find the option to show unavailable videos, so you may want to enable it manually before you use this extension. Once it also glitched out and started queuing videos instead of deleting them, this was fixed by reloading the page and running the cleanup again

Works as expected

works

Does what it needs to do, thank you :)

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storing stuff that i'll get back to for years and it kept bugging me, so i thought 'blow it, start again, they are all out of date anyway.'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

what a life saver, just removed 5000 videos! Took some time but it was good enough since for some reason the billionaires at google can't add a "remove all" button on the watch later playlist, I kept adding videos and forgetting about them for years!

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.
