Title: Enable shumway in private browsing window.

At the current implementation, Shumway doesn't run in private browsing window on Firefox even if we set `shumway.disabled` as `true`. I think that this is not good for testing for feedbacks, and this behavior confuse us for coherency of the configuration.
