We do the same thing in the sense that we all have data breach obligations and would do those things in such a situation. We've also put together our own version of that “have I been hacked” Firefox monitor. For Firefox account holders who opt into it, we'll actually notify them affirmatively of other attacks that we're notified about, not just any breach on our system but on others as well. I think that's going to be a service that people find valuable.
