Arch Linux

Is this still relevant? If not we can close it.

Yes, this is still relevant.

If this helps, here is a proposed patch:

```patch
diff --git a/thunderbird.desktop b/thunderbird.desktop

Why isn't this fixed in Thunderbird? Why should Arch carry a custom patch.

As far as I know the thunderbird.desktop file is currently already maintained by Arch as part of this package at https://gitlab.archlinux.org/archlinux/packaging/packages/thunderbird/-/blob/main/thunderbird.desktop.

I do not know of an official upstream maintained .desktop file, but it might be possible to use the one at https://github.com/mozilla/releases-comm-central/blob/master/taskcluster/docker/tb-flatpak/org.mozilla.Thunderbird.desktop.

I just downloaded the lastest package from https://archive.mozilla.org/pub/thunderbird/releases/115.1.1/source/thunderbird-115.1.1.source.tar.xz and yeah it has the desktop file at thunderbird-115.1.1/comm/taskcluster/docker/tb-flatpak/org.mozilla.Thunderbird.desktop.

I've diffed it with what Arch provides and the only relevant change (and, my guess, the rationale why a separate desktop file is in Arch) is that the upstream contains `Exec=thunderbird -compose` while Arch's version uses `Exec=/usr/lib/thunderbird/thunderbird -compose`.

Not sure if the upstream version could be patched during package creation or what's the best way to resolve this issue. (I'd also want to see the mid: support which the upstream already has included).

Is there a need to change the path? Arch provides a shell script at /usr/bin/thunderbird that calls /usr/lib/thunderbird/thunderbird and passes along all the arguments.

Application icon not being detected with upstream desktop file.

Icon=thunderbird in the old .desktop is now Icon=org.mozilla.Thunderbird so either changing it back or renaming the icons to match should work.

Since we are using upstream version of the .desktop file [1] we might as well rename the icons also [2]
