Hi I would like to disable kiosk mode in firefox, or at least disable the F11 key from toggling it, because F11 is too close to the backspace key on alot of keyboards and gets annoying.

You can use the Keyconfig extension to disable the F11 shortcut key.

Here is a simple extension to disable the F11 key.
Copy and paste the full DATA code in the location bar and press the Enter key.
Save the file as f11disable.xpi (3.0 - 6.*)
