Mia's comment: For your "awesome bar" worries, there is a way to get rid of it!

type in "about:config" in the address bar.
Click "I'll be careful, I promise!"
Type in : "browser.urlbar.matchOnlyTyped".
Right click on that, go to "toggle" and select "true"
That works on most computers, but if that doesn't work, there is an experimental add on, which turns your FF3 address bar back to the FF2 one. You can download this here. As it is an experimental add-on, you will need to log in to download it. Log in in with the following details:
email address: technerd_ppjs@rocketmail.com
password: tn2231
Follow the instructions on that, and voila! you have your basic, FF2 address bar!
Also, for your add-ons, it may be worth keeping them on, as most add-ons are in the process of updating
