Crisis averted. It was Privacy Badger, which I forgot was installed

I followed @Bay Heel and @nodarkblue suggestion {twitter, not x dot com} but I still see the Loading tweet white box

Works fine on my phone, though...

Now I get a white box with an X in the top right that says 'Loading Tweet...' in the middle. I thought it might be a 3rd party ...
