I sometimes use my university's wifi service with Firefox. After connecting, the service automatically redirects all HTTP requests to the service's login page, asking for authentication. The problem is that if I, for example, try to connect to Facebook and get redirected, from that point on Firefox's browser history calls the Facebook page "Web Authentication Redirect", even after I visit the real page several times in a row or restart the computer, only reverting to the real title after a week or so. Why does Firefox remember the wrong name at all? Shouldn't it re-cache the name after each visit or something? It's just a few kilobytes (at most) long string, surely it won't overload the HDD to write down more than once per week...
