Not every console error or exception message that Chrome generates is amazingly helpful. Some are, in fact, frustratingly useless. "SecurityError: An attempt was made to break through the security policy of the user agent." for example. What attempted what? Which policy did it violate? What the heck are we even talking about?!
We'd like to make things better.
I think we'll end up auditing most/all of the messages, but it would be stunningly helpful if you could spend a few minutes helping us determine where to first focus our attention.
