I had this problem, i'm no techy had it happen 3-4 times, always while using firefox, had some weird crap come up about phone being infected with virus, or I was taken to random porn sites, decided to clear cache on firefox, and am now using chrome instead, and no more crashing, yet.

Well, it's 10 months old. It was released on February 2016 so it's still under warranty.
