It happens here as well as far as I can see (tested on a Debian 11 server
running Django 3.2.12).
The "Chosen groups" box seems to be created by JavaScript; if I run it with
JavaScript disabled then it doesn't exist. Apparently JavaScript creates the box
and then populates it and accordingly removes stuff from "Available groups".
Therefore it could be an error in Django; maybe for some reason that JavaScript
doesn't always run correctly on Firefox.
If I were you I'd file a Django bug anyway.

I don't know how long this has been happening for me.
Happens on Windows 10 in Mozilla Firefox but not Chrome.
In the Admin User screen where there are two boxes of Groups labelled
'Available groups' and 'Chosen groups' with controls to move groups between
boxes, everything seems to work perfectly - until I refresh the screen!
On refresh, the Chosen groups box seems to slide across to the left and drop
all its groups into the Available box! It quickly resumes its usual place on
the right except that it is completely empty.
Shift refresh retrieves the data from the database and everything is OK.
The problem is that if an admin user accidentally saves after a refresh, they
save that profile with no permissions and that user loses all access to their
data.
I have tested identically on four different Django projects I look after with
the same results. Django versions 3.2.12 and 3.2.13 running on Apache 2.4 on
Ubuntu 20.04 and localhost on Windows 10 with the dev server. Also happens on
Ubuntu 18.04 with nginx and running Mezzanine.
Any ideas? Debug strategy?
Not sure where to start.
Seems like a Mozilla issue but I have been known to get things wrong. Has
anyone seen this?
Thanks
Mike
