customize toolbar with Add-on icon
How do I add the icon for an add-on which is not shown when I click on "customize toolbar"? When I click customize toolbar the result does not show any of the icons for add-ons/extensions.

You need to check to be sure it's a Firefox addon icon from the Firefox Addon site to see it exist there.
Not sure how to do that. When I look at add-ons extensions from the menu I don't see any way to add and icon.
You need to use the new extensions button. Your extension should be listed on it. Right-click it or click the cog next to it and select Pin to Toolbar.
