WebDriverException: Message: Socket timeout reading Marionette handshake data: Resource temporarily unavailable (os error 11)

Python Selenium stopped. This happened for the first time. So this is memo.. (confirmed work correctly with no changes, just after error).

Similar to this https://github.com/mozilla/geckodriver/issues/1470 . In this case, updating geckodriver is the solution.

This python is on Jupyter and waiting 10 hours loops. It might be the reason.
