As an aside, F5 in Firefox 3+ has a long-standing bug with iframes: the new iframe src= in the DOM structure is ignored, and Firefox makes a request to an older iframe src=. This also happens after session recovery. Another bug claims that iframe targets are sometimes mixed up, which implies some broken internal cache.
