78.4.0esr. Some cookies refuse to be deleted, or cliam to exist when they don't. At the moment I have a youtube cookie which, according to OPTIONS, SITE DATA, MANAGE DATA-CLEAR DATA, is there as "0 cookies, 276kb, last used 2 days ago." The entry won't delete. I've had other similar things, for eample cookies which will not delete manually but will when I closee FF. I've not had such problems with other FF versions.
Please advise. Thank you.

"0 cookies" should mean zero cookies.

276kb of local storage data sounds like quite a bit (mine shows 96.0 KB).

In the Manage Data dialog, if you highlight "www.youtube.com", click Remove Selected, then click Save Changes, then approve the removal in the popup, does that work?

Thanks. If I do that - 50 times - it asks if I want to clear, answer YES, that box closes, but the data manager popup box remains, it will not close until I 'X' the box.

The box remains, I suppose in case you want to remove other things, but the domain you removed should be gone. If it's not working on yours, it sounds as though Firefox might be having a problem deleting the storage files. In that case, you could do it by hand. In the profile folder, look for:

[profile.folder]\storage\default\https+++www.youtube.com

I think you can just delete the contents of that folder.

Also make sure that you do not use Private Browsing mode.

Maybe check this in the Storage Inspector with a tab opened to YouTube.
