I'm not sure about this since I use Google Chrome now and not Firefox. I wouldn't be surprised though. Firefox seems to be more for customization than actual speed.
Google does track your usage, but I don't think they can identify you with it as long as you don't allow check the box that says to send usage statistics to Google. If you do check that, then you send statistics that can identify you. If you don't check it, then you only send information that can't identify you.
