I have been having browser problems. I am running Windows XP. I just downloaded the Firefox (my default browser) updated version. I was having the same problem before I installed the update. I actually thought the update would solve my problem. It seems that even though Firefox is not running on my laptop (because I do not have the browser open at a particular point in time), when I try to open a session, I get a message that says Firefox is already open and that I have to close and restart. Is there an easy fix to this?
