how do I restore a deleted profile and then remove the profile feature completely so I never have to see it in my application menu again?

I dont want this profile feature at all it's a complete and total nuisance so I deleted the only profile it had for me but now everything but my bookmarks are gone and I need my settings restored. How do I completely disable this nuisance so I never have to see this annoying color bar in my application menu again? All my settings are destroyed now.
