My husband and I use one PC with two seperate accounts, why does he keep getting a update failure notice for Mozilla but I don't ?

We share one PC running Windows XP. When he opens his account he keeps getting first in the lower right hand corner that the updater is safe then a message box comes up that says " Update Failed make sure another version is not running and restart" When I Open my account no such message appears-why? Thanks-

Who has Admin rights on that PC?

If you don't have Admin rights you probably don't have "rights" to update Firefox, thus don't receive the "update message".

Try opening Help > About Firefox and see if you get a message about the update. And while you're in that window see if it says Firefox 27.0.1 or just Firefox 27.0 .


As far as the "Update Failed make sure another version is not running and restart" message, if your User Account was running in the background and you had Firefox open, that could cause Firefox not to proceed with the update in your husband's Logon User Account. Firefox needs all Firefox user Profiles to be closed as part of the update process. The user Profile that is initiating the update will close automatically, but the process will hang if any other Firefox Profiles are running in the background. I have that happen frequently when I am switching between 2 Logon User Accounts in WinXP.
