Recreating the Safe Mode short cut shouldn't be difficult for a "power user", non-sheep, who doesn't need the dumbed down interface, such as yourself. :uhh:
As Edmund wrote in his first reply... and as was written in the links provided by Grail Knight...
Right click the Firefox icon in the start menu, create another shortcut, go to the properties for that shortcut, and add
-safe-mode
in the Target box (see pic above). Then rename the shortcut to something more descriptive and put it where ever you want.
