Homepage, Toolbar, and Default browser settings won't stay after logging out and then back in.

We have Firefox ESR 17.0.7. Our Enterprise uses Firefox as our default. We are trying to figure out why we keep some settings and lose other settings. Upon logging out we lose settings like Home Page, Toolbar changes and making Firefox the default browser. We can set them but overnight the setting will not exist anymore. We have tried creating a new profile using the profile manager and even pointing the profile folder to a different location to see if that helps. But to no avail.

You probably do not use CCleaner, but if you do, or if you use another "clean up" tool that runs at Windows launch or shutdown, make sure to create an exception for the Firefox Profiles folder.
