I use different profiles for different tasks. I have an profile for streaming using a VPN and an other profile connect to my VNC-Servern using NoVNC (NoVNC is a client but has no GUI). All firefox instances lokk the same in panel - the normal red firefox icon. Is there a way to change this icon for each profile? I don't mean the icon i can customize in the *.desktop file. Can this be done with an other theme?
