KDE:  right-click on the application menu, "Edit Applications", 
Internet->Mozilla Firefox, edit the Command: entry so that it executes 
what you want instead of the default "firefox %u" command.

Everything:  Just find whatever .desktop file is being used by your 
desktop environment with "locate \*desktop | grep firefox" (there may be 
a few of them.)  Then edit the Exec= line so that it invokes the command 
line you want instead of the default "firefox %u".  This will almost 
certainly break every time firefox gets updated though.

Alternatively, copy the default .desktop file to wherever your Desktop 
directory is, then edit that, and always launch your firefox from that 
icon/whatever instead of the system menu.  That will get rid of the 
"menu entry goes back to default after update" problem.
