I have switched to the Beta channel in my Firefox some time ago. Now I want the stable channel back. Unfortunately it is missed from http://www.mozilla.com/en-US/firefox/channel/

For some reason they decided to get rid of the channel-switching feature.

Basically, I think you can just download and run the stable version installer, without having to uninstall anything.
