Toolbars are hidden. Ex: Diigo
I have installed the Diigo toolbar, but it doesn't show below the Navigation toolbar. I know the toolbar is there because there is a checkmark next to it on View - Toolbars. There is also a grey space below the navigation bar, where the toolbar should go. Thanks!

Hi,
You can try to Enable the toolbar in Tools (Alt + T) > Add-ons, if it is disabled. Please also try right-clicking on the name and Find Updates. Clicking on More and Home Page would take you to the support site. You can also try to Disable other possibly conflicting add-ons. If all fails, you can also try to Remove the toolbar and later install it via the search box on the top right or from AMO.
