Make Firefox’s toolbar buttons keyboard accessible

Mark “dive into mark” Pilgrim delivers a nice little extension for keyboard users:

Firefox toolbar buttons are not in the tab order; there is no way to reach them with the keyboard. This is an accessibility problem, because everything should be navigable with the keyboard. Actually, that’s a misstatement. It is more correct to say that every function must be possible with the keyboard. It is acceptable to duplicate each button’s functionality in menus, which are fully keyboard navigable. This is the route Firefox has historically taken…

It doesn’t work yet with dropdown menu type buttons, but it’s an excellent start: Tabbable toolbar buttons in Firefox.
