Firefox 29, Australis. Take 2.

I realized, after posting the last stylish post, that I'm quite bored with the dark. So I made it lighter.

I think this will be it actually, I think I'm satisfied (yeah right).

Also, this (Buttons Back) puts the reload button back in its proper place. If only I could put other toolbar items between the navigation buttons and the urlbar I'd be real happy, grrrrr.
