My browser opens blank, no page, no toolbars, and no options.
When I open my browser it doesn't display anything. It doesn't show the search bar, bookmarks toolbar or the orange Firefox button in the top left. I have to open it by right clicking on the icon in my desktop tool bar and opening it from there.

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: Command+Shift+F).
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible.
- Firefox menu button > Options
- View > Toolbars (press F10 to display the menu bar)
- Right-click empty toolbar area
Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.
- check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
- if "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette into the Customize window to the Bookmarks Toolbar
- if missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
- if you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar setup
