A question for whomsoever uses a Mac or an iPad and reads Facebook using the Safari browser:
When you're in your feed, or timeline, whatever it's called, is it scrolling and behaving all right for you? At some point yesterday it started jumping around and scrolling (in big jumps) uncontrollably, and that's continuing today. After all of these years, right out of the blue, that's what it's doing. But only on my "feed". When I enter a group page or anyone else's page, it behaves again.
It's happening on the MacBook, the iPad, and the iPhone. Oh wait, maybe I didn't try the iPhone. But the fix for it on the Mac just now is to use Chrome instead of Safari. I'll be trying that on the iPad next.
