Re: 答复: W3C Navigation Error Logging - log when UA crash/freeze?

Aaron, Liang, do you have any existing data on size of the problem?
Examples of how and where it helped?

I figure every browser maintains some internal tracking for crash counts
(we do with Chrome), but it's not clear to me that this data is actionable
for the developer. Many crashes have nothing to do with site's application
code, and often times its hard to figure out who's at fault (site vs.
browser bug, etc).
