Drag and drop not working to upload attachements using Flatpak

[lguerard]

Hi all,

I recently switched to the Flatpak version of Thunderbird when it got updated to 102. I just realized today that I can't drag and drop files to attach them to emails.

Is this also happening to other people (aka should I reinstall it) or is this reproduceable ?

Thanks !

Happening to me too, let me know if you've managed to somehow solve it since.

I have been managed solving this issue for me by setting filesystem=home. It seems like the thunderbird app needs this to be able to access files which are moved into a mail via drag and drop. I used Flatseal for an easy graphical option to change the settings.

Edit: I also had to move the profile folder after changing the filesystem settings, otherwise one needs to setup the account(s) again.

I consider that a bug. If the user wants to drag and drop something to an application, that's just the same as the user picking that file with a file chooser. Firefox has the same issue, see https://bugzilla.mozilla.org/show_bug.cgi?id=1786251

Yeah, I think fiefox needs to change something in its code to make it work with portals, then thundrbird will use it as well.
