I do not use an Admin user account for web browsing. Therefore, I have a standard (non-admin) user account which I use for web browsing.

I recently upgraded Firefox to v 67.0.4 from my Admin account, thinking that this change would migrate to all user accounts. It did not. In my daily use, standard user account, FF was still at version 66.0.3

Next, I attempted to upgrade FF directly from my standard user account by downloading the installer, then running it from my standard user account but (necessarily( with Admin credentials. This approach also failed, and FF in my standard user account is still stuck on v66.0.3

What is going on and how can I fix it?

When you install 64-bit Firefox with administrative privileges, it goes into

C:\Program Files\Mozilla Firefox\

However, if you don't have those privileges, Firefox may be installed somewhere under


Since AppData is a hidden folder, that is is most easily accessed using a shortcut (you can paste into the Windows 7 Start menu search box):


Anyway, for the less privileged user, can you use the internal updater as described in this article: Update Firefox to the latest release?
