I keep getting the error message [Cannot read property '$A' of null] when I try and add any component to the home page in Lightning App Builder. Am I missing something?

This is the error pop-up I get when I try to drag a component to the home page. I have tried creating a new playground. It happens with any component I try to add. Does anyone know what this means and how to fix it so I can complete this project?

    I was able to figure this out, in case anyone else is having this issue. I was using the chrome browser and I switched to Fire Fox and I stopped getting the error message. Not the best solution, but at least I was able to figure something out.
