Title: Displays errors and "Parameters" header in Firefox

Firefox was not displaying errors or the "Parameters" header (because it doesn't support innerText).
Once displayed, error text in Firefox would contain only the stack trace, not the actual error message (because Firefox's Error.stack does not contain the message itself).
