Each of these release channels has something to offer, the stable channel offering stability and reliability (of course), while the beta channel offers new features for the upcoming release. There may be some bugs and stability issues, but it will certainly be more stable than the aurora channel.

But after you’ve had your fun with the beta or aurora channel and wish to go back to back to the stable release or go from stable to a beta channel, how do you change it?

Previously you could change your channel by selecting the desired release channel in the About box, but Mozilla removed that ability recently for reasons I cannot find.
Change Your Firefox Release Channel

Alright, enough gibber-jabber, let’s get to it.

If you wish to change your release channel, all you need to do is download the proper release and install it, which will take you through an upgrade process instead of a full-on installation.




Change to Firefox stable – Download the stable release at www.getfirefox.com.

Change to Firefox beta – Download the beta release at http://www.mozilla.org/en-US/firefox/all-beta.html

Change to Firefox aurora – Download the aurora release at http://www.mozilla.org/en-US/firefox/all-aurora.html

So there may no longer be a way to change your release channel within Firefox, it is still pretty easy to do without that capability.
