I used to be able to open the bookmarks sidebar with an icon in my bookmarks toolbar along the top of my browser. However I got a new hard drive and lost all my previous applications and when I reinstalled Firefox (ver. 3.6.13), my little link/icon is gone.

I can still access the bookmark sidebar through View->Sidebar->Bookmarks or the keyboard shortcut, but would like my one-touch link/icon to open the bookmarks sidebar back. Is it still available as a link or icon, or am I stuck opening it using the drop down menu/keyboard shortcut?
