Panel Launcher Properties
 

RH9
I am putting commonly used programs on the panel.

Now for Firefox and Thunderbird, in the COMMANDS box in the Launcher
properties dialog box, I entered the path to the program
(/opt/thunderbird/thunderbird)

I just want to know if there is any parameter I should add to ?

thanks

I dont think so. Do you have problems launching the programs?
In that chase the path could be wrong.
