Thank you for your reply but I've already done everything you've mentioned here and the loading of the pages is still extremely, extremely SLOW. I have not always had this problem with firefox, It use to be very fast until I updated from 4 to 5 then 5 to 6 and now 6 to 7.0. EVERYTIME there was an update, and I was notified to update the browser and I did, this is when the slow loading of the pages began. I've tried everything, all of what you've suggested and other suggestions and nothing as worked. At any rate, thank you for responding...it just looks like I'll have to go back to IE or Safari...

Create a New Profile as a test to check if your current profile is causing the problems.

IF that New Profile works then you can recover your Bookmarks and Passwords from the Old Profile.
