I have been having trouble with Firefox since I updated it, have you? I will be doing just fine in it, but when I close out of it and then come back later it tells me Firefox is still running and I need to stop the process or reboot before I can reopen it. This has been happening ever since the upgrade to the newer version. I'm thinking it might be the new security fixes changed the firewall? If you're not having the same problem, do you have any suggestions to me to fix this? Do you think I should uninstall and reinstall it?
