Firefox/fix
In my recent video on compiling Firefox from source I forgot to fix the annoying problem of the duplicate icon in the GNOME panel.
In this appendix article I explain how to fix it.
There is a mismatch between the name of window open and the program executable.
To find out the name of the window you can give the command from the terminal:
$ xprop WM_CLASS
or press ALT+F2, type lg and select windows
In my building firefox it is firefox-nightly
Open the folder
/home/../.local/share/applications
Find the last launcher created with alacarte that will have the generic name:
alacarte-made.desktop
and add:
StartupWMClass=firefox-nightly
Save and restart Firefox.
