You have to hunt for it but they have a page where you can download older versions. Version 28 writes over 29 or the beta for version 30 and things are back where you had them. If you use the larger icons and/or the text below them, you will have to go into customization and reset those options. I turned updates from notify me of new versions to don't even tell me about them.

P.S. I wouldn't call if fixed in anything except location. I'd call it broken. I've got home, reload, print and a couple other icons between back/forward and the address bar.
