DEBUGGING Travis

The tests are running, and the Firefox tests are mostly passing. On the
User video test, though, it successfully checks the first two videos and
then goes out to lunch when it tries to browser.get() for the third.

Next thing: see if the branch passes if you only check one randomly
selected video instead of running through all three. This is not ideal,
but would be faster and would probably tend to test the video stuff over
time.  If so, merge that in (after removing all the debug).
