Altering the default keyboard shortcut to quit Firefox

I would like to propose an option to change the keyboard shortcut to 
quit Firefox from Ctrl-Q to Ctrl+Shift-Q.  It is a simple patch, but I 
do not know how people would react to it.  The benefit is that it 
removes the "feature" of accidentally quitting when only desiring to 
close a window or tab (Ctrl-W).  As you can see from the patch, this is 
the default for Windows, so it is not unprecedented.

I used to use userChrome.css to change it, but I have to resort to 
modifying the code due to limitations of more modern versions.

Is this something that would be accepted?  I wrote the patch to always 
be applied, yet it can be changed to be behind an option.
