So recently FF pushed their v29 update to the release channel along with their new them called "Australis" which imo was unneeded, it should be optional.
Basically it just in a sense chromifies FF,they removed alot of things including the addon bar and tabs on the buttom
to get it back to the old look just install this https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/
it will put the addon bar back, and put most of things back to where they were
it will also put an extra about:config option for tabs on the bottom
you can remove any redundant shortcuts with the built in customizer
