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?

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
https://cdi2tp.math.tecnico.ulisboa.pt/texto/4
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.
