As I said in previous posts, when this happens, I hover over the taskbar icon and hit the X, or use task manager to close Stealth Core. Trying to open again usually works. But I hasn't had this issue in a while... It happens once every couple months.
Perhaps reinstalling Firefox and making sure you have the latest version might help? If it's on your system anyway.
