You should still see the "Bookmark This Page" and "Show All Bookmarks" items in the Bookmarks menu.

Make sure that the menu bar is visible.

• View > Toolbars (press F10 to show the Menu bar)
• Right-click empty toolbar area

Firefox 29 and later versions have the Australis interface that looks different than the user interface in Firefox 28 and older versions.

• With the Australis interface the orange Firefox menu button has been replaced by the three bar Firefox Menu button at the far right end of the Navigation Toolbar
  A consequence of this new menu button is that you no longer can hide the Navigation Toolbar
• There is a star like button to the right end of the search bar on the Navigation Toolbar to bookmark the current web page and a "Show your bookmarks" button next to it to open the Bookmarks in a drop down menu.
  You can find "Show All Bookmarks" to open the Bookmarks Manager (Library) at the bottom of this drop-down list
• It is possible to have the menu bar visible via the right-click context menu on the toolbars to have menus like the Bookmarks menu

Thank you for the reply but I was already aware of all your bulleted points before I posted the question.

What I really want is to add the "Bookmark this Page" item to the list in the new bookmarks drop-down menu. I had hoped there would be a userChrome.css item I could add to accomplish that.

Some menu entries in the main menu bar are hidden if you use the mouse and only appear if you use the keyboard to open the menu. You can see the difference if you use Alt+F to open the File menu or other menus like the Edit menu (Alt+E) and Bookmarks menu (Alt+B) and compare that to what you see if you use the mouse to open the menu after you have made the menu bar visible by tapping Alt or by pressing F10.

• "Bookmark This Page" and "Bookmark All Tabs" (Shift+Ctrl+D) no longer show in the Bookmarks menu unless you open the Bookmarks menu via the keyboard (Alt + B).
• "Bookmark All Tabs" can also be accessed via the right-click context menu of a tab on the tab bar.
• "Bookmark This Page" can also be accessed via the right-click context menu of that browser page.

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

• http://kb.mozillazine.org/userChrome.css

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

/* Always show menu entries with class="show-only-for-keyboard" */
#navigator-toolbox menuitem[class="show-only-for-keyboard"]:not([hidden="true"]){ display:-moz-box !important; }

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

• http://kb.mozillazine.org/Editing_configuration

• Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
• Use a plain text editor like Notepad to create a (new) userChrome.css file in this folder (the names are case sensitive)
• Paste the code in the userChrome.css file in the editor window and make sure that the userChrome.css file starts with the default @namespace line
• Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css. Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
