Oh boy ! Here we go again instead of adding at .x in its version Mozilla has moved on to its new numbered version.

Full list of changes can be found #-Link-Snipped-#
Just go to Help > About Firefox and rest of the updating work will be done by the browser. Get it and post your views regarding this new version.
