Thunderbird startup error when using flatpak version on Debian 13

Hi all:

I was running thunderbird (v128.14.0esr) installed from Debian 12 (bookworm) repositories with no problems. My profile folder is on a network drive, I know this is NOT recommended but I am the only user and this configuration has worked flawlessly for several years. Recently I upgrade to Debian 13 (Trixie) and installed the flatpak version of thunderbird (v140.3.0esr) to get the more current version than in Debian 13 repos.

My problem is when starting the flatpak version, I get error "Thunderbird is already running but not responding". The "ps -ax" command does NOT show any process with thunderbird in the name and I cannot figure out what is wrong.

Here are the contents of my flatseal configuration/overrides file: [Context] sockets=inherit-wayland-socket;session-bus filesystems=/mnt/fserver/Applications/Mozilla/TBird/Profiles/Default;home;host-etc;host-os;host

[Environment] MOZ_NO_REMOTE=1

My profile is located at /mnt/fserver/Applications/Mozilla/TBird/Profiles/Default and I can access it from my Debian system.


Any suggestions would be greatly appreciated.
