Tested with:
Device: Samsung Galaxy Note 5 (Android 5.1.1)
Build: Firefox for Android 44.0a1 (2015-10-05)

Steps to reproduce:
1. Go to

Expected results:
- Video automatically starts to play

Actual results:
- Video doesn't start to play automatically (even if 'Allow autoplay' pref is enabled)
- A black screen is displayed. After tapping the screen, video controls are displayed
- After the 'Play' button is tapped, nothing happens.

- also h.264/mp4 videos are not working either on
- regression:
good build: 03-10
bad build: 04-10

Can we get a regression range on inbound or fx-team ?
Teodora - Your changeset is a backout of bug 1186745. Bug 1186745 has landed again. Can you retest?

This is irritating. We need to get it fixed. Why didn't tests catch this?
This looks like a regression from bug 1209850.

We never reschedule an update once an update was scheduled before the decoder's initialization was done.

I don't see how that could have prevented YouTube to work however. Isn't MSE enabled on android?

Resolution: --- → FIXED
Target Milestone: --- → Firefox 44
Verified as fixed on latest Nightly build (10-20-2015), on Samsung Galaxy Note 5 (Android 5.1.1)
Does the fix apply to Firefox 45 on Android 4.4.4?
If it should I suggest checking the video on page
This video works on any current desktop browser or other mobile browsers for Android 4.4.4.
That particular video WFM, but I would recommend filing a new issue if you're still having video problems on that site Joao.
