Ref: http://www.mozillazine.org/talkback.html?article=6590

"In a standard Firefox installation, only the Mozilla Update sites
(update.mozilla.org and addons.mozilla.org) are on the whitelist by
default. This has allowed the Mozilla Foundation to apply a server-side
change that prevents attackers from exploiting the code execution flaw
using its systems. Therefore, **if you have not added any additional
sites to the whitelist**, you are not at risk from the code execution
exploit and have not been since yesterday. However, you will still be
vulnerable to the less serious JavaScript injection flaw."
