After getting to the installer portion of the Roundcube installation, I had to reboot the server.
After the reboot, Firefox browser no longer loads.
I tried deleteing the Mozzila folder from the home directory. Rebooted - made no difference
dnf remove firefox
Reboot
dnf install firefox
It still won’t load. I double click on the icon, get the whirly ball for a while and then NOTHING.
Depends on wether you are running X11 or Wayland.
If running X11, any stderr from started GUI programs are stored in ~/.xsession-errors
Don’t know, where Wayland stores those.
But:
What always will show any errors, is starting it manually from a shell running in a terminal window. If there are any errors logged by firefox, you should see them right in that terminal window.
