After upgrading to 24.04 Thunderbird has migrated to snap, and now I got 4 copies of my Thunderbird profile.
$ du -sm snap/thunderbird/*/.thunderbird/v* .thunderbird/v*
11783 snap/thunderbird/507/.thunderbird/vwsjq0wp.default
11783 snap/thunderbird/509/.thunderbird/vwsjq0wp.default
11730 snap/thunderbird/common/.thunderbird/vwsjq0wp.default
11782 .thunderbird/vwsjq0wp.default
current points to 507
$ ls -ld snap/thunderbird/current
lrwxrwxrwx 1 kfc kfc 3 Sep 2 00:25 snap/thunderbird/current -> 507
However common seems to be the folder which gets updated.
I know that ~/.thunderbird can be deleted, but I still got three copies of my profile.
Which can I delete, and how can I prevent snap from creating more duplicates when Thunderbird gets upgraded?
