Type "About:About" in the address bar without the quotes. Now you have a menu of many of the About commands without having to add anything to Firefox.

NOTE TO br2: You can edit the code. I added About:Addons because it wasn't included.
Then I minimized the whole thing to be just About:About.
And then I eliminated it :)
