Discogs importer continues dissapear

[adolfoboo]

Hello to all

After working for a couple of days, the Musicbrainz import icon disappears again.
Script version provided in issue #777.

Tested in Firefox, Chrome, and Brave [latest versions].
Tampermonkey, GreaseMonkey, and Violent Monkey [Firefox].
Tampermonkey and OrangeMonkey [Chrome].

Cleared cache in case it was a glitch
Uninstalled extensions and reinstalled. Same problem

Is this happening to anyone else?

Thanks in advance
