I can embed twitter and youtube by link. But it doesn't work with Facebook, dailymotion and Vimeo.
How to embed it?
P/S: How to changed width and height of embed content ?
Did you ever figure this out?
For some reason, Vanilla 3.3 can embed Facebook posts, using the m.facebook to denote mobile - hopefully a
bug that will be fixed in 3.3 or perhaps 4.x in the future.
