You should use the Firefox ESR branch then. Details here: http://www.mozilla.org/en-US/firefox/organizations/ http://www.mozilla.org/en-US/firefox/organizations/ tl/dr; summary: 12 months of security only releases. Each year the ESR branch is rebased on the current version of Firefox. I believe Firefox 17 will be the basis for the next year of ESR releases.
