The [[Install]] algorithm in particular has changed significantly, and [[Update]] now returns the promise returned by [[Install]]. This needs an overhaul.

Test case for updatefound. Expected output in the console: 1 2 wfu wfu-setup wfu-done wfu-updatefound 3 Actual output on Firefox maple 35.0a1 2014-10-06 1 2 wfu wfu-setup wfu-done

Hi Nikhil, I was looking into the reason why our Blink SW test suite had such a low pass rate (*) on Firefox. I think this is because updatefound is not triggered, we rely on this for a lot of the tests. So we end up waiting for ever and asserts are never reached. See attached test case. There is at least one more class of issues. I will see if I can find out what's going on. *: https://docs.google.com/a/chromium.org/spreadsheets/d/1d0nh5sz2tyuBQCzKFtvEuBP0JcaQw8EuFcxSCbmRpYs/edit#gid=1800943783

Maybe Firefox is so fast at sending the updatefound event that we are not seeing it before we have a chance to setup the listener? I'll try to find a way to modify our tests to avoid this potential gotcha.

The test passes for me as described in comment 1 on mozilla-central.
