How to make FVD opens only when click home-page-icon, and not open when open new tab ?

There is a browser add-on that will do it for you. Speed Dial will open as homepage, but tabs can be controlled to open with an option of your choice. Some offer choices of what type of tab page and others simply open a blank tab.

Can you just say what add-on it is?
