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 */

#bookmarksMenuPopup scrollbox,
#bookmarks-menu-button scrollbox,
#PlacesChevronPopup scrollbox,
#PlacesToolbarItems scrollbox {overflow-y:auto!important}

#bookmarksMenuPopup autorepeatbutton,
#bookmarks-menu-button autorepeatbutton,
#PlacesChevronPopup autorepeatbutton,

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

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)

I clicked up to Show Folder...what do you configure from there?

Thank You

I finally found it. After you click on the bookmark icon you Now have to click on View Bookmark Sidebar and it takes you to the bookmarks that I am used to. (when you clicked on the bookmark icon it used to take you directly there)

You can install the Classic Theme Restorer extension to have a button in the Customize palette to open the bookmarks in the sidebar.

• Classic Theme Restorer: https://addons.mozilla.org/firefox/addon/classicthemerestorer/

You can check the settings of the CTR extension via its Options/Preferences button on the "Firefox/Tools > Add-ons > Extensions" page.

The code for userChrome.css I posted above adds a scroll bar to various bookmarks menu drop-down list.

• 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.
