Why don't I see tweets automagically in my browser anymore ? [View all]

When DU first started auto-loading tweets, I found it kind of annoying, but now there are so many posts with tweets it's kind of a waste of time having to do the two-step process just to see one line of text or one pic. I don't remember doing anything to turn tweets off, but I think they stopped after I upgraded Firefox (NOT positive about that) or maybe after I changed some uBlock Origin settings. Anyone have the same experience ? What's the fix ?
