Hi AG-Ubrio, the profile that you should check is not the lightdm one,
but this:
/var/lib/snapd/apparmor/profiles/snap.firefox.firefox
It doesn't matter much, though, since this also has the rule
/tmp/** mrwlkix,
Can you please check in the logs, if you get some apparmor denials when
running firefox? You could run the command
journalctl -f -t audit
then start firefox, and paste here the output from the first command.
Also, if you say that the directory is created, it would be interesting
to know what are its permissions.
