You should keep in mind that the use-case for Firefox is that the default install focuses on the general user, and add-ons are intended for people looking for something extra/different. You can get the add-on bar back easy by grabbing the 'classic theme restorer' add-on. It allows enabling-disabling a variety of features.
I can't say I agree with all of their choices, but I'm running 29 right now and I don't feel like any functionality or customizability is lost from the last version. If you're not looking for the defaults you can change pretty much everything you want with a few add-ons and about 10 minutes or so of configuration.
