Can you please update the corresponding loading stories (which you might need to
add) to have the same URLs (+logins if applicable) as the ones you use here?

[Hannes Payer (out of office), 2016/08/04 11:38:01]

Added imgur to the load stories.
Changed the links in the browsing stories to be the same as in the load stories.
Done.

IMO this (and the corresponding mobile story time) should be longer: when I ran
these locally (on a fiber connection), there was barely enough time for the
video to load before we moved on to the next story. What about increasing the
time to something like 10 seconds, but cutting the number of pages to something
like 1/3 of what it currently is? That seems like it would more accurately
reproduce how people use YouTube.

nit: invalid indentation. The two basic options are:

  # Line break when needed + vertical alignment.
  facebook_login.LoginWithDesktopSite(action_runner, 'facebook3',
                                      self.credentials_path)

  # Immediate line break + 4 space indent.
  facebook_login.LoginWithDesktopSite(
      action_runner, 'facebook3', self.credentials_path)
