It also might be something much more mundane such as a bug in the browser which occurs when you have 100+ tabs open and tries to write to a misaddressed memory region.
It may well be some malloc()-like routine returning 0, saying "no more memory for you buddy" and the code blindly dereferencing that value and causing a write to the 0-page. It is a common error with sloppy coders.
