Unable to copy a script from the editor

[flarn2006]

Whenever I select all and copy in the built-in editor, pasting just gives me a single - character. Considering I don't know of any other way to export scripts, this is a big problem.

Oops sorry; I was in a rush and annoyed at the time I reported this. Here you go:

Operating System: Arch Linux
Firefox version: 69.0.1
Greasemonkey version: 4.3
Exactly which script, if any, is causing a problem? It's one I made. I'd post it, but the only way I know of to get it out of the editor (see also #3053) is by copying it to the clipboard, and of course that's not an option.
Exactly which page, if any, is exhibiting this problem. Well it's the script editor, so I guess moz-extension://1b5a7ce0-a8d3-41eb-b985-98bb4ea6c884/src/content/edit-user-script.html.

Actually, after doing some testing, it appears that this happens any time you attempt to copy more than 1,001 characters.

I just copied 57,450 characters out of a script first try.

I've never experienced this issue either (just some delays in copying/pasting). So could it be something specific to your system?

Can you try with this script?

@flarn2006 I've tried it with that script, but I could copy the entire script from the GM editor into an external text editor just fine.

[flarn2006]

Ah okay; must have just been on my side then. Sorry to waste your time!

@flarn2006 OK, I hope you manage to solve the issue!

Edit: Oh, this whole issue was fixed by #2894 which was GM 4.4 - hence the above issue using 4.3.
