Only Facebook Container. I tried allowing CC in it, but it made no difference. It does appear to be a Firefox-related thing though - I just tried Chrome and the previews work in it. What's my Firefox doing that Dogtrousers' isn't?Do you have anything that blocks popups and tracking such as Ghostery running as a plugin to your browser? I get this too but have always assumed that it is Ghostery.
Thanks! On my phone at moment but will try that.It might be worth having a look at your Firefox security settings. If it's set to "Strict", embedded tweets look like your example.
I think they made a change a few updates ago so that Strict became the default.
