Has anyone found a solution to the problem of Firefox (3.0.11) hesitating for seconds before responding to mouse clicks? I've searched the Web and can find nothing but frustrated users and one or two reports of "no solution". Windows XP SP2 firewall is on and there is no interference from a virus checker. Secondly, rant: an increasing number of companies are closing their e-mail channels of support, pre-order information, etc., and directing you to useless FAQ pages or other pages with inadequate options that don't accommodate your specific needs. I could scream.
