I really like the FF browser. I would like to use it for all my work. However there are some sites that cause FF to become very slow and eventually stop working. Some sites I have identified are the A to Z database, Territory Helper, and sometimes Google Maps. I can use these sites in Chrome with no problem. Eventually I'll have to close FF using the task manager. My FF only has 2 plugins, Bulk SMS, and FVD Speed Dial. And neither of these are in use for the problem apps. There are no error messages generated. Thank You.
