Details

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

Using the firefox snap version 133.0-2 (revision 5361) from the latest/stable/ubuntu-24.10 track, when using the file chooser dialog (Ctrl-O) the following denial message is seen in dmesg / journalctl -k

Dec 03 09:12:32 graphene kernel: audit: type=1400 audit(1733179352.920:1320): apparmor="DENIED" operation="open" class="file" profile="snap.firefox.firefox" name="/etc/fstab" pid=15197 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

This can be resolved by adding the mount-observe plug to the snapcraft.yaml
