Going to the quote.csv URL gets this 403 message:
"It has come to our attention that this service is being used in violation of the Yahoo Terms of Service. As such, the service is being discontinued. For all future markets and equities data research, please refer to finance.yahoo.com."
So I'm guessing unless there's somewhere else that data is available and this widget can be patched, this widget is toast. :(
