Does anyone have any idea what this warning/error means in firefox:
Unexpected value align parsing preserveAspectRatio attribute.
It appears to be an issue with the youtube iframe embed method. I had the same issue and it's solved if you use the old embed method (HTML tag).
That looks like that there's a preserveAspectRatio
attribute set on an element that isn't getting parsed correctly.
