Well I am a long time user of FF and I do try to familiarize myself with it. Customising the toolbar was one thing I had to do when they changed to their latest look, I was really use to the Home and Refresh/Stop button before the address bar.

Anyway now he has two bookmark options. Your option is good if you have frequently visited bookmarks because they can be added to the toolbar for quicker access but it does sacrifice a tiny bit of the window space for the webpages.
