Firefox is preventing me from going on line and receiving complete e-mails, including graphics. There is a continuing error message on allowing Firefox to update my computer, but then telling me that I must close the application before it can do that. To the best of my knowledge, the application isn't open. Short of shutting down my computer, how do I close this application? I was advised to uninstall Firefox and then re-install, but I cannot run that Wizard because the application is apparently open. Looking for help in closing the application.
