moving to IE from firefox

I am moving from using the firefox browser and would like to try IE8.It seem I am unable to get an auto prompt to save a login when I sign into identity protection-do I have to enter each login manually?This is just a trial type thing--firefox seems to be very slow and I am getting a lot of lockups.So I thought I would try IE just to see how different it is since I last used it

Thank you Pat
