Mozilla Quickstarter runs an instance of Mozilla in background.
As I still don't detect if there is any instance of Mozilla running, you should close all your Mozilla applications before start it.
The window of Mozilla that MozillaQs creates will show the url of your home page in Mozilla. If you don't like this you only must add about::blank in your preferences.
I have some translations pending, but I was not able to include them due to some problems with my project of kdevelop.
Also I would like to include some icons, but I have problems with them too. So you must have installed the crystal icon package for run MozillaQs perfectly.
The reason for deleting the other applications (composer, chat and addresbook) from the menu is that they cause some problems (they don't use the perfil that the user is using)and you should launch they from a new instance of Mozilla that you launch from MozillaQs (I have this problem in Fedora Core 2 without using MozillaQs and I don't know how to solve this)
