The request is similar to https://forum.snapcraft.io/t/auto-connecting-the-system-files-interface-for-the-firefox-snap but for thunderbird
Thunderbird allows sysadmins to define enterprise policies to customize the browsing experience. These policies are stored in
/etc/thunderbird/policies/ on the host filesystem, which is typically not readable by a strictly confined snap.
A plug is going to be added to thunderbird
This is a request for the corresponding store declaration to auto-connect the interface.
Thanks for considering it!
