You can hide the text on the Bookmarks Toolbar with code in userChrome.css.

Add code to the userChrome.css file below the default @namespace line.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#personal-bookmarks .bookmark-item > .toolbarbutton-text {display:none!important}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

It's not about hiding it. What I am saying is that I cannot even add them there. I can only add "Bookmarks Menu" and "Bookmarks Tool", but neither are Booksmarks tab which add it right below website bar..

The Bookmarks Toolbar does appear immediately below the address bar.

But maybe you had moved the tab bar below the address bar and were using pinned app tabs (they show only the site icon and not the page title)?

This is a picture of what it looks like.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible.

• View > Toolbars
• Right-click empty toolbar area

Use "View > Toolbars > 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
