on the latest Firefox (50.1.0) on Mac, I can't focus the links at all if I tab?

Yes, I have the same experience on Mac, though it's a different issue from this bug. :(

Yes, I have the same experience on Mac. I will file a new bug for this since it looks a different issue. :(

For this originally Windows issue, I tend to think it's something we'd like to fix in the near future (i.e. P2) since it's quite annoying and obviously broken. 

Hi Neil, I've seen your fingerprints around the code for |nsFocusManager::ScrollIntoView|. So I am guessing you perhaps know what's up here. Also do feel free to re-set the priority if you see fit. Thanks!

This is correct on Mac. You can press Ctrl+F7 to toggle the full keyboard access setting to enable tabbing to links.

The main issue is the same issue as 1278864. It requires a new flag to the ScrollIntoView, probably implemented as part of 1290152.
