I, for one, am absolutely fine with this. I have updated FF recently and didn't even notice any changes, had to look up what had changed after stumbling on this comment. I interact with address bar a lot, copy-pasting parts of URL all the time.
As long as they don't by default hide https:// and parts of URL from the address bar itself in Safari/Chrome style , I'm ok with it not shown in suggestions.
(I have a big 24" screen though, maybe that affects somehow).
