Do you mean the main toolbar with the address bar and standard icons (home, downloads, bookmarks, etc.)? What do you still have showing, if anything?

Note: in case you triggered Firefox's full screen mode, you can press the F11 key to switch back (F11 turns full screen on and off).

I have my all my tabs but before I had a Mozilla Firefox tool bar above the search bar. Also, how do I remove a tool bar that I do not want.

You can use one of these to set which toolbars to show.

• "3-bar" menu button -> Customize -> Show/Hide Toolbars
• View -> Toolbars
  You can tap the Alt key or press F10 to show the Menu Bar
• Right-click empty toolbar area
