Scan list not working anymore

[kirst-const]

Clicking the toolbar icon only shows a small bar / border, but not the list of websites:

The sidebar is also empty:

This started a few days ago. I've tried disabling all other extensions and themes, but it didn't help. Background scanning seems to work just fine. Exporting all websites to bookmarks works just fine, too.

FF 95.0.2 64-bit

Any ideas? Thank you very much for your work!

Go to options and open 'scan list' in a new tab. Then open a console (Ctrl+Shift+K) and copy all errors and warnings. Paste them here.

Creating a backup, un- and re-installing the extension and restoring the backup fixed the problem, btw. The extension now works again. Thank you for keeping up the good work!
