Extension works but cant change extension preferences (all shown as unset). When I open extension preferences, it shows the message:

The settings of extension [email protected] had an error:

• Distro: Ubuntu 24.04.2 LTS
• GNOME version 46
• Extension Version 37

I'm not sure if it has anything to do with it, but it seemed to show error after I reinstalled my firefox, which was blacklisted before reinstallation. I wanna fix it so i can blacklist firefox once again.
