I've just installed Firefox Developer Edition using the .tar.bz2 on the officiel website. I created the following .desktop to have the shortcut :
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Firefox Developer Edition
Exec=/opt/firefox/firefox
Icon=/opt/firefox/browser/chrome/icons/default/default128.png
NoDisplay=false
StartupWMClass=FDE

How could I do to have the same behaviour as the Messenger application for exemple ?
Thanks in advance
