Firefox does not give me a window when launched. Sometimes it takes a while and I get a window. Sometimes I give up and kill the process. I always have multiple processes of firefox running after I start it even if it does not have any windows.
A lot of time I get a popup dialog that I have a firefox process running already.
One of the firefox processes are <defunct>.
You’ll find the solution to this problem in the update thread’s common issues post (link below). Click the 3rd option under 2023-06-04.
xdg-desktop-portal-gnome has an issue in 44.1 on non-gnome desktops. You can revert back to 43.1 and it should fix the issue.
If you arent on gnome … why would you want xdg-desktop-portal-gnome ?
Unless you are running Flatpaks, you can do without it on non-Gnome desktops.
