Hi DRC,
starting firefox from the command line, like you proposed, works. But I
get some messages, I don't know, how to assess:
$ DBUS_SESSION_BUS_ADDRESS= firefox

But starting firefox this way is an emergency solution in my eyes. Are
you sure, that it's not possible to make the snap version of firefox
startable via icon inside the TVNC session, like any other regular
application?
Uninstalling the snap version of firefox and reinstalling it through apt
seems to be a bit difficult and error-prone. There are many different
recommendations in the web, which steps should be done therefore to make
firefox working properly, when installing with apt on Ubuntu 22.04.
Currently I'm unsure, which of those I should consider or not. Finding a
proper one will take some time. I would have to see, when I will find
that time.

My suggestion regarding dbus-x11 was to Felix and was pertaining to a
different issue.
Try unsetting DBUS_SESSION_BUS_ADDRESS, e.g.:
$ DBUS_SESSION_BUS_ADDRESS= firefox
That works for me. Apparently this is a known issue with snap
applications running in VNC:

You can work around it by uninstalling the snap version of Firefox and
reinstalling Firefox using APT.

Hi,
I'm not sure, whether this has been asked here already. Since
upgrading Ubuntu from 18.04 to 22.04 and TurboVNC from 2.2.7 to 3.1
I'm unable to use firefox inside the TVNC session. The firefox icon
is not visible in the dock on the left side and in the list of
startable applications. But it is definitely installed on that
machine. And when I sit locally in front of it, firefox is present in
the dock outside of the TVNC session and startable. When I try to
start it inside from a terminal shell, I get this:
$ firefox
/user.slice/user-700.slice/session-c2.scope is not a snap cgroup
I googled this and found several solution proposals. But they all
look strange to me (maybe because I'm no Linux nerd). Can anyone tell
me, what's the correct and best solution to make firefox startable
inside the TVNC session again? By the way, dbus-x11 cannot be the
reason, since it is installed already.
