Birdtray cannot detect Thunderbird state

[kojid0]

OS: Zorin 17.1 Pro, gnome, based on ubuntu, kernel 6.5.0-44-generic, wayland
Birdtray version: 1.11.4, installed as flatpak
Thunderbird version: 128.0.1esr (64-Bit), installed as flatpak

Unfortunately, Birdtray seems to be unable to detect Thunderbird state (already running or not). I set up Birdtray like this:

Whenever I close Thunderbird, Birdtray starts Thunderbird. But the crossed icon remains after that. When I double-click the icon, it gives an unknown error occurred while starting Thunderbird.

Same as me and hide function don't work.

In X11, all is ok but in Wayland problem happen

Same here, since the latest Nobara/Thunderbird updates, Birdtray does not work correctly. Essentially, it’s not capable of detecting whether Thunderbird is running or not. Additionally, it throws an unknown error when trying to execute Thunderbird using the built-in command (/usr/bin/flatpak-spawn --host flatpak run org.mozilla.Thunderbird), which runs perfectly from the Terminal.

+1, can confirm the same thing happens on KDE Plasma 6 with wayland backend.

/usr/bin/env MOZ_ENABLE_WAYLAND=0 /usr/bin/thunderbird
Set this as your Thunderbird command line in Birdtray

[ui-boris-huang]

/usr/bin/env MOZ_ENABLE_WAYLAND=0 /usr/bin/thunderbird Set this as your Thunderbird command line in Birdtray

The flatpak version can set to
/usr/bin/flatpak-spawn --env=MOZ_ENABLE_WAYLAND=0 --host flatpak run org.mozilla.Thunderbird
