Every time I open Firefox, I am asked if it is ok for Mozilla to make any changes. I think it is because I cannot seem to open it as anything other than the administrator.
Check that Firefox isn't set to run as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).
