Since today/reboot no file explorer anymore in Firefox

[imc67]

Maybe a coincidence but last night I did a server reboot and this morning some users discovered that the File Explorer tab in Nextcloud is blank/empty, it doesn't show any file while there is a 123GB with files and searching for files makes it possible to find and open. A stop/start of the app didn't helped.

After some debugging I discovered that it was only on Firefox and gives a lot of browser console errors and warning (see below). In Safari Nextcloud File browser does work but with same warnings (no errors) as in Firefox.

Does anyone know what this could be?

@imc67 one way to solve it (temporary?) is to clear cache and cookies
