AH yes, I highly recommend that you turn off cursor tracking while browsing 
Facebook with Safari, and it probably would not be a bad idea when viewing 
twitter either. In Facebook list of people that have liked a post, are expanded 
when focus moves to them, videos start playing and I believe the list of 
comments also is somewhat automatically expanded / contracted as focus moves. 
For this matter, I find best results with Facebook on Macintosh is to use the 
J/K to move next / previous through posts but this only really reads the posts 
when you have changed Web navigation from Dom to Group. 
 I remapped the enter key on my  numpad so that enter moves keyboard focus to 
VO cursor, and shift enter moves VO cursor to keyboard focus. There are a few 
places in the Macintosh environment where if cursor tracking is turned off, 
then VO click actions do not behave the way they should. I suppose if I was a 
good blind citizen I would report all of these to Apple. Certainly one other 
advantage of turning off cursor tracking is that you don’t get as many 
instances of VoiceOver repeating items as both Keyboard focus and VO focus move 
into new windows.

When VoiceOver was first shipped, they really pushed the group navigation mode 
on the web, but that is no longer the case. Sometimes it is nice as with 
Facebook there are usually descriptions and/or label names for the articles 
regions so that speech is limited to the appropriate level you don’t see the 
reactions or portions of comments until you interact with the posting article. 
There are some circumstances where group nav on the web causes links in the 
middle of a paragraph to be read either before or after the rest of the content 
in the paragraph, but I don’t think this happens with Facebook and group nav.

Of course all the above experience is associated with High Sierra or earlier 
versions of MacOS.

Take care!
