Comment 19 for bug 551748

So I get this to work finally by copying the .desktop file for the built-in firefox, changing the values in the file, then dragging the new modified firefox.desktop file to docky.

Not user-friendly, intuitive, or any of that, but it works.

Since I'm using LMDE, i noticed Firefox 5 hit debian testing so there's not much point in me using the custom downloads any more. No problem. Docky wants to use the built-in firefox so bad, this should be easy. I remove my launcher from docky, launch the new system default firefox 5 and the icon in docky still has my old "Firefox5" label on it, not the system default "Firefox Web Browser" label.

Deleting my downloaded firefox folder and the accompanying firefox.desktop file from the system results in a generic application icon (still with my old label) when I launch Firefox from the menu or command line. Pinning this to the dock and attempting to launch firefox does nothing (it bounces twice and does not launch the application).

It's the same problem in reverse. I can't get the built-in icon to work with docky now without having two icons. If this is not broken, then we're using a different meaning of the word. Are the icons/launchers cached somewhere? What causes this?
