"Add to Speed Dial" is missing in drop-down context!!!!!. Cannot add a new Dial.

Firefox updated today to 56.0.2 despite that I had selected not to update without my permission. That meant: suddenly I have no way of adding a website to speed dial. The context is completely missing.

All my existing dials are all there, no problem with sync either.

But I cannot add anything to any group from the drop-down menu...i.e. "Add to Speed Dial" -

Am also not sure if that is now normal: it shows the new interface for sync, but above that I still see all icons from the older version [where to customize speed dials etc. I do not see any problem in the dashboard panel if Speed Dial - but have now this major problem that I can no longer create a Dial, therefore rendering FVD incapacitated for the most important function :(.

I hope to find help as soon as possible.

PS: I do have a manual backup of course of speed dial as well as bookmarks.Just in case. Aside from the eversync online recovery versions.

What I have tried: disabled all other extension/addons in firefox [one by one] to see if any other addon would create a conflict. Resulting in: no conflict present. Enabled each addon also one by one to double verify. Also - no conflict. I uninstalled FVD and eversync. rebooted my computer, re-installed eversync and FVD - still the same problem exists.

Just to say this: the ONLY reason I even still look at Firefox is because of FVD. I would have ditched FF a few weeks ago at the first taste of disaster coming. Especially since most of my addons show the LEGACY ugly yellow face.
