Just updated to Firefox 31.0 and my Bookmarks Toolbar disappeared.
Using Windows 7, I have Classic Theme Restorer but uninstalled that and still had same problem. The Bookmarks Toolbar is where it should be in Customize mode and when I exit Customize I can see my Bookmarks Toolbar for a split second but then it's gone for good. Just started happening today July 24 2014 when I rebooted. Thanks.

Is the Bookmarks Toolbar items still positioned on the Bookmarks Toolbar?
Try to click the "Restore Defaults" button in the Customize palette to restore the default toolbar setup.
You can check for problems caused by a corrupted localstore.rdf file.
Thanks that restored it but for some reason the Bookmark Toolbar Items can no longer show now when I place them to the right of the navigating icons (Download arrow, home button, etc.). Thanks for the help!
The Bookmarks Toolbar item probably collapses to only the overflow chevron (>>) if you place that item in the Navigation Toolbar where you have the location/address bar and the search bar that also have a flex attribute and take all available space.
