Problem with Firefox upgrade

more options

I tried the suggestion to download Firefox and upgrade Symantec Endpoint Protection. It does not work. The Symantec Endpoint Protection is disabled when I try to use Firefox. Is there a way to get the old Firefox back? (PS: I do not know if I am posting correctly. This is the first time that I have asked questions on this site.)
