It's true that it wasn't widely used, but it seems as if Mozilla did their best to make it that way. It wasn't exposed to the user by default, but instead was hidden as something you could get to by the toolbar customization screen, so you had to modify the toolbar to even get access to the feature. I don't think most people even knew it was there.
