ctrl-J behavior is fixed on the tip for the "new" command line
interface. There is some more work being done there before we release
that code to bespin.mozilla.com, though.
The backspace button issue is actually something that showed up in FF
3.5b4. Other versions (including Shiretoko nightlies, I believe) do
not have that problem, so I think that was a regression in Firefox.
