When I hit Firefox icon, I get a gray page with message - Location: chrome://browser/content/browser.xhtml Line Number 741, Column 15: There is no way to close this window without shutting down the computer so trying to reload Firefox doesn't work because it tells me to close down Firefox. I have read the info given to others with similar problems. When I go to Programs - there is a long list of things listed under Moxilla Firefox. None giving a name similar to what has been given to others to use. I really need help. I am not computer savvy. This is possibly related to update by Microsoft, but not sure. This whole process has made it so I can't even get into my Outlook email, they want me sign up as new. I wish I could talk to someone on the phone, but I know the problem of those offering help for a big price.
