The story of 30 FF bugs
One of the main news of the last week was about 30 serious bugs found in Firefox. Comments posted just after that are very interesting and show some important thing: about people reactions, the way such thing can cause FF vs IE flame-wars and so on.
Finally, it looks that it was just a joke. It's still worth it to think about an emergency plan when something like that happens to your most important application. Or if it's worth acting at all.
