Steps to reproduce:
Opened a pop up window on my bank that referenced a different domain which did not have whitelist rules yet in umatrix. I could not see the toolbar and thus could not fix the whitelist to enable the page to work.
The popup window did not show the toolbar even though this preference was set to true.
I have this setting to true. In previous versions of firefox, this means that websites cannot disable to toolbar. It is critical that the toolbar be always visible, as umatrix is accessible from this toolbar, and many websites require tweaking.
Regardless of my specific use case, if a preference has been set, it should actually do something.
