See the similar question Firefox plugin to simulate slow internet connection or limit bandwidth? and its top answer to find the FF plugin Firefox Throttle and IE Plugin Internet Explorer Throttle.

If you have Firebug installed in FF, take also the YSlow plugin into consideration. It gives you a lot of information on the performance issues with your pages.
