TippingPoint vulnerability patched in Firefox 3.0.1 and 2.0.0.16

Issue

    So “10 fucking days” has slipped to “One fucking month”?

    As I mentioned in an earlier post (http://blog.mozilla.com/security/2007/08/06/mike-shaver-ten-days-and-expletives/) we try to fix security vulnerabilities as quickly as possible, but are not working with 10 days (or any other specific time frame) as our goal.

    This issue got a bit of attention, but it is about the same risk to our users as an issue of the same severity found by an internal Mozilla tester. Since the details were not made public, the risk to users is minimal. We still work hard to get those fixes out as soon as possible, because that is the best way to keep users safe.

    Some of us would prefer not seeing the childish use of potty words by your less mature users. Perhaps,you would consider blanking (yes, censor their little tirades) their nasty little comments, which add nothing of value to the message.
    I feel certain you do everything possible to keep up with all the latest virus threats, etc., and some of us do appreciate it.
