Firefox loads as a white page including the menu bar

I open Firefox and everything is white, menu bar and everything, I can't see any of the buttons, I have to minimise the window to the task bar and back again to see anything but its not live, I can see everything but I cant see my pointer or text courser but it is clickable and I can see the text change on the task bar but I then have to minimise and back again to see the page, this is the same for scrolling and anything I wont to do on the page.
