Version 0.4.2 is entirely broken in Firefox

[SayanthD]

Nothing is working in Firefox and since it doesn't support "background.service_worker" with Manifest v3, I can't manually load this extension from the source at the latest commit. But its fine, the real problem is that button-functions aren't working in here.

Using Firefox stable: 111.0.1 (64-bit)
Extension version 0.4.2
Installed from https://addons.mozilla.org/en-US/firefox/addon/get-cookies-txt-locally/

The source code in the master branch does not support Firefox.
The firefox branch contains diffs for it.

We have confirmed that the version currently available on AMO works with 111.0.1.

I am very sorry, I misunderstood your issue.
As you said, I have confirmed that it is not possible to export or copy.
I am now investigating the issue.

If you want to debug, please use the firefox branch as mentioned earlier.

v0.4.3, which resolves this issue, is now published on AMO.
Thank you very much for reporting this critical bug!
