Comment 3 for bug 1504853

Actually, a browser change might not be needed. For non-overridable errors, the browser doesn't present any buttons in the error UI which means that the only way to dismiss the error is hit the back button. This still works correctly with my proposed changes, because CertificateError.cancelled fires.

If the browser presented a dismiss button in the error UI (which I thought it did when I suggested we might need a browser change), then the browser would need to ensure the CertificateError is deleted so that Oxide removes the placeholder transient page that gets inserted. That doesn't appear to be the case though.

So far the browser is working fine with my changes
