I have upgraded firefox to 8.1 on Windows 7. On administrator account all is well shows the new firefox look. But on a restricted account, firefox says it is not up-to-date, but the properties of both short cuts are pointing to the same updated firefox file. Both about versions are the same as you would expect. It seems to me the permissions have some to do with this. I am a programmer. I have tried to reinstall the firefox under the administrator in many different ways on the restricted account but to no avail.
