Well Mozilla does warn you by default if you go back or reload a page that'll trigger a form submission, so it's already got a partial defence against that.

Secondly it is possible (although not the most fun task!) to write server-side apps defensively so that they will ignore, discard or query duplicate form submissions, and really this is the only way to do it that you can be sure of.

If you rely on any browser based mechanism to deter duplicate form submissions you're relying on users using specific versions of specific browsers that implement the specific features you want, and in the real world that is rarely realistic.
