Can't find any way to do this in Firefox, though I did find this in StackOverflow
Currently there is no way to show the values of getters within the Firefox DevTools, but it is already filed as bug 820878. Tried to use Chrome, but this cannot load from localhost because no Access-Control-Allow-Origin same as Firefox had. I never use Chrome so no idea how to fix this in Chrome.
