Epiphany already does this, which has saved me a bunch of times when clicking a link by mistake or in some other way fumbling out of a form I was filling out.

Now, sometimes this isn't a problem, because you can just navigate back, and the form data has been cached. But loads of times this doesn't happen because of some AJAX dynamics or some other JavaScript functionality that renders the form.

It should be a small, but very useful fix.
