My Model X has had the browser freeze to a white screen about weekly since I have owned it. It has been to Tesla twice including right now for this and some other issues. My loaner car is a 2014 Model S and it has done the same thing! This must be a generic problem. You do the 2 scroll wheel reboot and the browser is fine for a few more days and then does it again!
I assume others must have this issue.
