Custom Persona does not display after updating Firefox!

Question

== Issue
==
I have another kind of problem with Firefox
== Description
==
I just updated Firefox, and my custom persona is no longer displaying properly. If I change to another persona from Mozilla it will display it just fine, and I can even see my custom persona when I mouse over the button that you would use to select it. But as soon as I move the mouse away or click to select it, it reverts to the previous persona. What can I do about this?
== This happened
==
Every time Firefox opened
== As soon as I updated yesterday
