We had several meetings with the Shield team and decided that we would not move forward with the Shield study. It turns out just having Min Vid enabled was a substantial hit to Firefox’s responsiveness. Slowness was the #1 feedback we got from Min Vid surveys. We thought whatever we learned from the study would be tainted by that and reflect badly on Firefox. Unfortunately, we’re also unable to rewrite it as web extension APIs don’t exist for what we were doing.
So, https://medium.com/firefox-test-pilot/min-vid-graduation-report-9ad74dc37c1 is still the best summary for what we found and the question of implementing in Firefox has been turned over to the Firefox team. I don’t expect Test Pilot to do any more with Min Vid.
Sorry your patches never landed. Thanks for taking the time to send them.
