That's already a problem, though. In fact, some form of it may well be Bruno's current problem, at least if "Instant" ajax search is turned on. After all, in that case the results page would have been about blue roses when it was first visited, and only later ajaxed itself into being about red roses as the result of some keypress events. So on browsers (including Iceweasel, FWIW) where you do see red roses when you return to the page, something clever is happening, probably to do with all the ajaxy bits rewriting the current page URL.
