After Update After the update to 5.7, there is no possibility to edit groups for regular users

Hello,

After updating from version 5.6 to version 5.7, there is no possibility to edit groups for regular users. In version 5.6, there was a gear wheel “Manage users and Groups” in the top right, which disappeared for regular users. Now only admins can see it there. Is this a bug or a feature of version 5.7?

I found out that it was a problem with the old version of the add-on for Firefox. There is already a new version of the add-on in Chrome and Edge, and it seems to be working fine there.
