How do I add a space to the toolbar in Firefox 29.0? I can grab a space from empty areas and move it around, but where do I find a "space" icon to ADD a space?

Question

It has been useful in past versions of Firefox to be able to add (a) space(s) between icons on the toolbar in order to create groups of icons and/or separate icons by class or function. In Firefox 29.0, I discovered how to "grab" (click and drag) a space from open areas on the toolbar and move it to another part of the toolbar. But how can I add spaces to the toolbar? In past versions, there used to be a space icon in the customize menu set that could be dragged to the toolbar for that purpose.

You can get around this problem by installing the "Classic Theme Restorer Add-on" available at: https://support.mozilla.org/en-US/kb/how-to-make-new-firefox-look-like-old-firefox
While returning the squared-off look to your tabs, instead of the newer, rounded version - it also gives returns the option to add spaces; variable size spaces, and separators to your tool-bars.
