24: Firefox: How can I fix Dark Theme / Firefox 56 when using PolicyPak ?

Cause:
It seems the Firefox set the following settings inabout:config

This can occur if you’re using PolicyPak Application Settings Manager (and the Firefox 23 and later Pak) to REMOVE all AddOns.

Since THEMES are also AddOns.. Firefox then defaults downward to the DARK theme.

Resolution:

Choice 1: Use PolicyPak to force an Add-on which is a Theme that you want.

Choice 2: In our lab, problem goes away when we set the settings as shown in this screenshot:

lightweightThemes.SelectedThemeID = empty
lightweightThemes.usedThemes = true

To fix this on all your client machines please use FirefoxAbou:ConfigPAKs and set the above value as instructed. Here is just a reference screenshot:
