It appears that opinions differ on what the proper behavior of the Backspace key should be (personally, I prefer Previous Page), so perhaps it should be a user option: O Page Up O Go Back O Do Nothing
i thought users could already do this w/ some profile file
Timeless, most real users don't want to edit a .js or .xml file! lol
Reporter: there was talk about creating general keyboard configurability at some point. That would allow users to assign they keystrokes to whatever functionality they like. Should this bug be subsumed by that?
See http://www.mozilla.org/unix/customizing.html#keys for information on how to set up custom key bindings. It only works for commands which are exposed to XBL, but page up/down are selection commands so they are exposed (see the editor bindings in htmlBindings.xml for the commands to use).
Bug 57805 is the one for a general key remapping UI. It's helpwanted, and isn't likely to get fixed any time soon unless someone contributes a fix or at least a start on one.

I am not sure, if it was a good idea to mark this feature request as duplicate to 57805. It is probably much easier to enable configuring just one key in the user interface than creating a user interface for configuring all or most of the keys. There has been many discussions about the backspace behaviour in firefox on linux. I know, that it can be configured in "about:config", but this not convinient and absolutely not obvious to linux-newbees. Linux should be a real alternative to Windows. Now, that firefox has got so popular, and internet gets more and more important, sometimes even replacing desktop-functionality, people can think of switching to linux. Let's make the switch as easy and comfortable as possible.
