When I open Firefox, there is a white screen that opens for just a moment then goes away. Then Firefox will load as normal. I say normal but it is running kind of slow. Any ideas as to what this flash of a screen is about? Thank You

I'm not sure what the flash is, but you can try refreshing Firefox. Refresh Firefox - reset add-ons and settings
