org.mozilla.Thunderbird (aka net.thunderbird.Thunderbird)
Thunderbird for Flatpak installation instructions are available by clicking here to visit the Thunderbird app page on Flathub.
Non flatpak-packaging issues should be reported upstream at
https://bugzilla.mozilla.org/describecomponents.cgi?product=Thunderbird
To use an old, non-Flatpak Thunderbird profile copy it from
~/.thunderbird
to
~/.var/app/org.mozilla.Thunderbird/.thunderbird
In case Thunderbird opens a new profile instead of the old one, run:
flatpak run org.mozilla.Thunderbird -P
then select the old profile and tick "Use the selected profile without asking on startup" box.
(#3) All supported locales are available in org.mozilla.Thunderbird.Locale extension. One locale that matches host OS locale will be installed and selected by default. For instructions about how to enable more locales in flatpak take a look at https://flatpak.readthedocs.io/en/latest/flatpak-command-reference.html#flatpak-config
(#90) Dictionaries availability is similar as for locales. They also could be downloaded manually from:
https://addons.thunderbird.net/language-tools/
and installed through:
Menu Bar > Tools > Add-ons > Extensions > Install Add-on From File
You may need to restart app in order to make changes effective.
(#11) To enable new mail notifications:
- Menu Bar >
Edit>Preferences>Advanced>General>Config Editor…, setmail.biff.use_system_alerttotrue(default) - Menu Bar >
Edit>Preferences>General> SelectCustomize…for "Show an alert" and set "Show New Mail alert for:"
(#79) Alternatively you may set mail.biff.use_system_alert to false which will make notifications non-native but clicking on them will open mail in Thunderbird.
(#75) To enable the experimental Wayland backend (assuming the desktop session runs under a Wayland) set:
flatpak override --user --env=MOZ_ENABLE_WAYLAND=1 org.mozilla.Thunderbird
(#51) For Smartcard support you need at least Flatpak 1.3.2.
