this vshare search thing is NOT very good. how do I get rid of it?

Any vshare extensions in Tools > Add-ons > Extensions ? See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

You can also do a search on the about:config page via the Filter bar at the top for vshare and reset any prefs found to the default value via the right-click context menu.

See http://kb.mozillazine.org/about%3Aconfig

I don't see any vshare toolbar anywhere and there's nothing in add-ons, extensions or anywhere else...this vshare thing is just not very helpful or very intuitive. Change is NOT always a good thing.
