I am not sure if its an error message. I am working inside of Firefox, developer tools. When I try to add a widget, the console says:
TypeError: mutating the [[ Prototype ]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[ Prototype ]] value using Object.create and below this message in a different color text, it reads
"destroy widget [ themes/jewerlyBoxTheme/widget/HeaderController/Widget]" &
"widget [themes/JewerlyBoxTheme/widgets/HeaderController/Widget] created"
