Firefox accepts any key after back-button, if callback had loaded a new page

[mspreij]

I have this code:

KeyboardJS.on('e', function() {
  location.href = location.href.replace('a=view', 'a=edit');
});

This works well - it loads the edit page.

But if I then hit the backbutton instead of submitting the edit form (or clicking any other link on that page), the same function is then run on pressing any other regular key (characters, numbers, punctuation etc), not just 'e'.

This happens in Firefox 17.0.1 on OS X (ML) and Ubuntu.
Safari and Chrome work as expected on OS X, and Chromium on Ubuntu too, so it's a FF issue, looks like?

This has to do with firefox caching the JS state of the previous page. Its an annoying thing that they've done for a long time I believe. I don't think its fixable. If I find time I'll reopen this bug and see if I can find some sort of solution.
