Bookmarks UI ConsolidatorBookmarks UI Consolidator
This extension moves the Bookmarks menu from the menubar to the Bookmarks toolbar.
It also makes the toolbar keyboard-accessible. It puts the toolbar between the search box and the browser's tab bar in the tab order, so when you press the tab key in the search box (or press the Shift-Tab key combination while on the browser's tab bar), Firefox will focus the toolbar, and you can then use the arrow keys to move through the toolbar's items and the space bar to open its folders.
