Comment 23 for bug 60995

Arwyn, your proposal doesn't fix anything, as accidentally pressing AltGr+Backspace instead of AltGr+- or AltGr+$ or whatever other keys are next to it on your keyboard would cause the same dataloss (actually AltGr+$ = "]" on Belgian keyboards, so this isn't an really uncommon combination to press for almost anyone using a web forum).

And the same potential for data loss is there for every possible way to implement this functionality (including the current Alt+Arrow ones and the back/forward buttons on the toolbar).

There are probably hundreds of different ways to get the same type of data loss in Firefox currently; you can't remove all those keys, key combinations and buttons, because there would be no useful keys/buttons left.

I agree that this sort of data loss should be prevented, but this should happen in a sane and clean way (and it can be done; the Firefox developers just have to take the time to do it instead of adding new "features").
