Right-clicking navigation bar opens menu with the "customize" option greyed out. How can I activate that greyed-out Customize option? Thanks.


Normally, right-clicking an empty space on the navigation toolbar opens a drop down menu with "Customize" at the bottom. I have used this feature for many years. Tonight, it is greyed out. The drop down menu still appears when I right click between tabs, but the "Customize" option is non-responsive.

How do I show and hide the different toolbars?
It's your browser — most toolbars can be shown or hidden depending on your needs:
To show or hide a toolbar, right-click on an empty section of the Tab Strip and check or uncheck it in the pop-up menu.
Menu Bar: This is the top toolbar that contains the browser menus (File, Edit, Help, etc.). On Windows Vista and 7, the menu bar is hidden by default and its features are contained in the Firefox button. If the Menu Bar is hidden, you can temporarily show it by pressing the Alt key.
Tab Strip: This is where your tabs are displayed — it can't be hidden. By default, the Tab Strip is above the Navigation Toolbar. If you want it below, right-click on an empty section of the Tab Strip and uncheck Tabs on Top. For more information, see Why are tabs on top?
Navigation Toolbar: This is the toolbar that contains website navigation buttons, the Location Bar, the Search Bar, the Home button and the Bookmarks button.
Bookmarks Toolbar: This is the toolbar that contains your Bookmarks Toolbar Folder bookmarks (for more info see, Bookmarks Toolbar). On new installations of Firefox, the Bookmarks Toolbar is hidden by default.
Add-on Bar: This toolbar is located at the bottom of the Firefox window and contains buttons associated with your extensions (if they are made available by the add-on developer). See What is the Add-on Bar? for more information.

How do I customize or rearrange toolbar items?
You can easily add, remove and rearrange items in Firefox's toolbars.
Right-click on an empty section of the Tab Strip, select Customize... and the Customize Toolbar window will open. (It doesn't. It's greyed out.)

Question owner

I posted this question, and I want to report that the problem disappeared when I shut down and reopened Firefox. The "customize" option is now acting normally again.

I had this problem in Firefox 7.0.1. After customizing once, "customize" was always disabled until restart.

Disabling StyleSheet Chooser Plus 1.2.2 fixed it.
