Is there anyway of making your own shortcut on Firefox for exiting?

i know Alt + F4 / Alt + W

but i got this extension that makes it go to the system tray cos my sister always closes it and i dont want her to.

so is there a way i can get Alt + E to exit firefox?

Firefox 2.0
Windows XP Professional

help? thanks

Since you have professional, this should work:

Create a shortcut (doesn't matter where you create it) and in the "target" box of the shortcut properties type: "taskkill /f /im firefox.exe" and then click shortcut key and press the keys you are interested on and then click OK.

However, doing that may not allow firefox to save what it wants to save. You can sorta "fix" this by removing the "/f" (force) switch which will ask firefox to close, which will save what it needs to save.
