If you are running Firefox, Thunderbird or Mozilla under Windows, you need this patch right away or you will still be vulnerable to remote exploit. Users of other operating systems are not affected; the vulnerability is in Windows, but Firefox has been patched to work around it.
If you have just gone through the inconvenience of installing Firefox because of the vulnerability in IE, my heart goes out to you. I hope you'll take comfort in the fact that a fix for this problem is already available in Firefox and Mozilla (within a day of the exploit being published), while it seems there is still no effective fix for the problem in IE, so you still made the right choice.
