"The application firefox-bin has unexpectedly quit." This keeps happening when I am using firefox. All is fine and then the beach ball comes up, spins for a few moments, firefox crashes and then I get the above message. It also says that no other applications have been affected. What does it mean and how do I fix it? I have replaced firefox and it does not seem to help. I am using a Blue and White. Running10.3.9 with 512 mb of ram. I appreciate any help you can give me. Blake
