I have used Firefox for about 2 years. I recently downloaded the latest version and since then ( one week ago)--whenever I open my hotmail account, within one minute of scrolling through emails Firefox becomes "unresponsive". I have to close and open Firefox about 3-4 times before is becomes "stable" and I can use my hotmail account. Why is this happening. Ironically I switched from Internet Explorer to Firfox because of the same type of problem with Explorer.
