How to remove icons from a toolbar in firefox

I've just updated my toolbar in Firefox, I accidentally hit restore default button, which brought back the default set.

There are two icons, namely Home and Download, that I don't need - but I can't figure out how to get rid of them.

I've tried dragging them off the side when in 'customize toolbar' mode, but they won't go away, any ideas ?

Answer

Right-click on the toolbar (not inside the search bar or the address bar) and select "customize" from the menu, then you will be able to drag and drop the desired icons on the toolbar.

Specifically, to remove them from the toolbar, you don't have to "drag them off the side", but drag them inside the new window that will be opened and that contains all available icons.
