Using Thunderbird (edge) as an upgrade to the default version fails, because the snap uses a non-standard location for the user-profile. Any existing profile will be stored in ~/.thunderbird but snap uses ~/snap/thunderbird/common/.thunderbird/
The official way to tell Thunderbird to use an older, existing profile would be entering thunderbird -ProfileManager in a console, but the profile manager has no ability to look for a profile in a different directory.
You can try just copying (or moving) the entire existing thunderbird profile from ~/.thunderbird to ~/snap/thunderbird/common and you should be good. Pretty sure I did this when I migrated from the traditionally installed thunderbird to the snap.
Note that the chromium snap has some logic to import an existing profile the first time it is run.
This requires the personal-files plug to be connected.
There’s something not user-friendly here.
Alan’s tip does not work. TB --profile-manager does not take account of the new data.
Running TB 78.2.1 (edge channel at the moment) I had to:
- launch TB snap
- close TB snap
- delete the snap profile’s folder content
- copy all the old profile folder content in the snap profile folder
- launch TB snap
- remove all the unused langpacks in TB extensions menu (to have full native language in TB)
- restart TB
It did, but Mozilla changed the on disk format in the newest release (since my post) and there’s no migration as I understand it.
Well, I migrated FF and TB to snaps. Seems to work very well. Still the first run quite slow (using i7+NVMe…), but you know that.
Do you know why LibreOffice or Snap Store snaps still do not render my fonts correctly (Roboto from Ubuntu repo) ? Because fonts are fully ok in FF and TB snaps (spacing is as in deb versions). I do use Wayland GNOME session.
Last question : since some deb versions, FF does not respect default UI font in search bar. But I notice it’s ok using the snap. Why ? (Please note this snap better behaviour than deb for future use. )
Last last question : will TB be a Canonical (as author) snap ? I know Kevin is yours, but Canonical is not a one-man-team and FF snap is from Canonical.
Currently experiencing the same for Thunderbird 91 (candidate).
I believe this happened after the update because I remember checking them earlier this week (last update at the time of writing is August 27).
~/snap/thunderbird/common/.thunderbird/, and it created a new profile. My old profile is still there, and still accessible when I ran
snap run thunderbird -ProfileManager
This is a known issue that is being resolved.
