On XFCE (Archlinux) I have the problem, that thunderbird leaves workspace 2 and comes to workspace 1, when I click on a "new email" desktop notification. I have tried to set thunderbird to stay "always on this workspace" but it did not help.
If this is a bug, could it be a thunderbird or an XFCE bug and can I somehow stop this behaviour?
I want thunderbird to be permanently open and maximized on workspace 2.
