Configuring Firefox Nightly - screenshot but no waterfall

Does anyone have advice on configuring Firefox Nightly on a private instance in EC2?

So far I’ve managed to get Nightly installed on the windows image, updated the wptdriver.ini, and it fires up in response to a test started via the web interface.

I get a screenshot back on test results, along with timings… but no waterfall and no content breakdown.

I’m wondering if I’m doing something wrong. Possibly something in the profile template needs to change; I’m using the regular firefox one.


It should “just work”. I just updated the nightlies on the public instance to the latest 32 release and it looks like it’s working ok:

Are you running the latest and greatest agent (at least from the 2.14 release if not newer)? If not that’s probably the issue.
