This has been in Canary for a while and it is, now, in Dev. Favs Bar has more variations available. Can see it all the time, not at all or only on New tab. And, remember, doesn't matter which is selected, Ctrl+Shift+B, still, makes FB show or not.
Personally, I rather like Never & then, Ctlr+Shift+B for the brief moment I need to make use of FB. Remember, too, one does not need to see it to Add to it.
