Hi cipricus,
This is a security feature working as intended. Ubuntu recently decided
to disable unprivileged access to user namespaces. You can find more
information it about it here:
https://ubuntu.com/blog/ubuntu-23-10-restricted-unprivileged-user-namespaces
https://discourse.ubuntu.com/t/spec-unprivileged-user-namespace-restrictions-via-apparmor-in-ubuntu-23-10/37626
https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2046844
It was included (but turned off in 23.10). In 24.04, it has been turned
on.
We have been adding apparmor profiles for most packaged applications.
Saying that, firefox downloaded from tarballs or other places don't come
with an apparmor profile, so the mitigation isn't relaxed for them.
You can enable user namespaces by either making a apparmor profile for
your firefox installs, making sure the directory where firefox is
installed is correct in the profile, or by just enabling user namespaces
for your system. There is instructions to do this in the first blog
link.
Thanks,
Matthew

Status in linux package in Ubuntu:
New
Bug description:
All details are to be found in my previous bug report
(https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/2056190).
Given that simply reverting to kernel 6.5.0-17-generic fixes the
problem, the bug seems to be with the 6.8.0 kernel. Therefore I'm
posting this.
