Can confirm that this works on Firefox 3.0.3 on Leopard.

You don't need to create a new tab simply selecting the bookmark and having it load is enough to send Firefox into an infinite loop.

It's not hanging the product or really loading anything. You've called document.write() which opens the document, but it's not finished loading. You have to call document.close() to trigger the onload event that stops the throbber.
