Firefox suddenly won't open. It will load in my Processes (Win XP) and show itself as running at only 3,604 K memory instead of the usual 30-something and it will not launch a browser. I tried uninstall/reinstall. I tried backing up my profile. I tried DELETING my profile. I tried deleting both the mozilla folder under Programs once the uninstall was complete AND I went into the Application Data folder and deleted that, too, THEN reinstalled. Still the same problem. No other programs are running at the same time and I have shut down everything running in the background (like iTunes Helper, etc) from the Process Tray. Right now, I've switched to Google Chrome, but I'd love to solve this and get my firefox back Any more suggestions? The help section doesn't tell you want to do if switching up your profiles -doesn't- work. Thanks!
