<p>And that the latter is a form submission</p>

<p>I suspect that the different behavior springs from some sort of usability helper in firefox which infers a "open in new tab".  This can be confirmed by clicking on the "help" link in both pinned (open in new tab) and unpinned (open is same tab) tabs.</p></div>
