/* Creates a statusbar at the bottom of the window by using bookmarks toolbar */

/* Since it's really the bookmarks toolbar you should move bookmarks away from bookmarks toolbar - for example to menubar. You can do that with Customize Firefox mode */

/* If you want to show the page-loading status in the statusbar then put a single flexible space as the leftmost item in the bookmarks toolbar */
/* By default this flex-space will take 50% window width to show the loading status bar */

/* Toolbar buttons/items will be aligned to the right edge of the loading bar. If you wish to align them to the right edge, then add another flex-space after the first one */
