All my unity-webapps work with chromium, except for Facebook. It popped up the bar to ask me to install, I did, and the unity-webapps-facebookmessenger package was installed. However, it does not appear in the dash or launcher.
I think I've traced the problem to a missing .desktop file in ~/.local/share/applications, all the working ones are there but Facebook isn't. However, I don't know what the contents of the Facebook .desktop file should be so now I'm stuck. Any suggestions?
