Description Fernando M. Muniz 2024-11-03 23:06:23 UTC

This happens once in a long while.

Sometimes when clicking on the Flatpak-Firefox icon, the system seems to process a little and give up, making me have to click again to actually run the app.

Comment 1 Nate Graham 2024-11-04 20:11:42 UTC

That means it failed to launch or quit/crashed immediately after launching. There are many reasons why this can happen, and we'll need to know which reason it was. Here are some ways you can figure out what it might be:

1. Run `coredumpctl --reverse` to look for crashes.
2. Run `journalctl -f` and then try to launch it again. See if anything interesting-looking is printed there.
3. Run `flatpak run org.mozilla.firefox.desktop` until the problem happens, and see what gets printed to the terminal window when it does.

Good luck!

"Not installed" but it actually is. (Edit: Shouldn't have included ".desktop")

I have no idea why the command isn't working.

Comment 3 Nate Graham 2024-11-05 18:14:19 UTC

It sounds like there's something wrong with the Flatpak installation on your system. I'd recommend debugging that first.

Comment 9 Fernando M. Muniz 2025-01-05 00:00:46 UTC

It seems that it only happens once per boot, and so far it takes about 30 attempts to reproduce the issue.

Comment 10 Fernando M. Muniz 2025-01-05 01:45:11 UTC

Just witnessed a Private windows not opening while already having a normal window open and working fine.

Comment 11 David Edmundson 2025-01-07 13:17:02 UTC

Please ensure you have the "Wayland windowing system" permission enabled for the flaptak. 

In any case, I'm afraid this is not a kwin issue if other apps can connect fine, sorry.

"Wayland windowing system" permission is enabled.

"Wayland windowing system" permission is enabled and it only fails once-in-a-while.

Any idea where should I file this? Wayland? Flatpak? Firefox?
