Firefox 34 beta won't be released until 11-25.

Firefox 33.0.3 is the current release version; the 4th "33" version released since 10-14.

There is no direct "update" from Firefox 33 to Firefox 34 beta. Once you're on a "channel" you are on that "channel" until you actually install the other version. And I have never heard of Firefox jumping back to another version unless the user inadvertently had both versions installed, and the desktop shortcut "got its wires crossed" and Windows pointed it to the wrong executable file.
