Thunderbird crashes on launch after latest upgrade

FWIW nothing at Troubleshooting Firefox helped.


For those interested, I opened a bug report at bugzilla. You can find it here.

I found that this was caused by having GTK_USE_PORTAL=1 set in my environment, which I had done to allow Firefox to use native KDE file dialogs. Apparently a Thunderbird update introduced code that causes this to make it crash on launch. See

Try unsetting GTK_USE_PORTAL and seeing if that helps!

KDE integration with (regular) Firefox

Wow I never would have thought of it! Unfortunately I already reinstalled Manjaro since this issue was driving me mad, but thank you nonetheless.

Yeah this was basically user error. :frowning:
