Youtube short not downloading

[jarmake]

Your question

This spesific youtube short doesn't seem to downloading on any mp4/mkv resolution option. https://www.youtube.com/shorts/p1ZuBJQJHi0. Tried closing and reopening browser but it didn't help.
The error console shows:
Exit code: 1 moz-extension://65e5b0c1-8485-4d4b-83ff-88aac62c58e6/background/main.js:1 receive@moz-extension://65e5b0c1-8485-4d4b-83ff-88aac62c58e6/background/main.js:1:13135 bd</callCatchAppNotFound/</<@moz-extension://65e5b0c1-8485-4d4b-83ff-88aac62c58e6/background/main.js:1:42669

It wasn't working yesterday, today the short worked.

Yep. Works now for me too.

Glad I found this discussion - yesterday a YouTube Short would not download, so I waited, and then today it did. In between I also closed and reopened Firefox. Mysteries of technology.
