I am trying to install Firefox Dev and followed this: How do I install the Firefox Developer Edition?
I created, with nano, a file: firefox_dev.desktop
in ~/.local/share/applications/firefox_dev.desktop
[Desktop Entry]
Name=Firefox Developer
GenericName=Firefox Developer Edition
Exec=/opt/firefox_dev/firefox
Terminal=false
Icon=/opt/firefox_dev/browser/icons/mozicon128.png
Type=Application
Categories=Application;Network;X-Developer;
Comment=Firefox Developer Edition Web Browser.
And I'm stuck; how do I launch it?
Exec=/opt/firefox_dev/firefox/firefox
An invalid .desktop will not show up in the Dash.
