Hello, I am facing some problems while updating Mozilla firefox on my computer. The operating system on the computer is Windows XP. I use Mozilla firefox to access the internet. The problem is whenever I try to update the browser, the update procedure starts and then it gives an error that the firefox is running and needs to be closed, click on OK to terminate firefox. When I click on OK, both Firefox and update procedures quit. Due to this I am not able to update the firefox. Is this some virus problem? If anybody is facing Mozilla Firefox download problem then please share some information about the same which may help me in solving the issue.
