I suspect that current stable snap for Thunderbird 78.7.1 has some problem with dbus.
When trying to save an attachment (direct save or save as), a line like the following shows up in the kernel log (dmesg), and nothing happens (no file is saved or no dialog shows up)
[87873.665529] audit: type=1107 audit(1613202544.939:1543): pid=1401 uid=103 auid=4294967295 ses=4294967295 subj==unconfined msgindent preformatted text by 4 spaces='apparmor="DENIED" operation="dbus_method_call" bus="system" path="/org/freedesktop/hostname1" interface="org.freedesktop.DBus.Properties" member="GetAll" mask="send" name=":1.757" pid=21770 label="snap.thunderbird.thunderbird" peer_pid=27920 peer_label="unconfined"
As far as I understand there is not interface in this snap to allow this.

Does anybody know a solution or a workaround to this problem?
