So somehow I've never noticed this as a problem. We get full stack traces for everything. On the other hand we use the hosted version of Sentry (https://getsentry.com), but since everything is open source, we bundle their raven library (https://github.com/getsentry/raven-js) into our CDN served package. So window.onerror is set from the same JS as the rest of the app. I'm guessing that avoids the cross-domain issue?

My understanding is that if your website and error-producing-JS file are different domains then you'll have an issue still. I think raven-js does some other stuff regarding letting you rethrow Exceptions, which would still work, but window.onerror is probably not reporting much in most browsers. Could that be the case?
