I've created a script located at the URL above which shows that Mozilla retains (and fills in) form values between page reloads. I believe that this behavior is incorrect and undesirable for dynamically produced pages. Directions are given at the URL for how to duplicate the behavior. I'm using Linux build 2001081514.
Thanks for the cool testcase, Leston. *** This bug has been marked as a duplicate of 46845 ***
