On startup, FF loads 2 tabs - one is my default, the other a FF info window.
I turn on my desktop and click my Firefox (FF) icon. When FF loads to the screen, two tabs appear. - one with some FF page that includes a FF video
it says something like "Hurray: your browser is up to date."
- the other is my default page The result is a slower loading time. Please help me avoid the FF-with-video tab on start-up.
