We've added millions of Firefox users since the move to the faster cadence. Another thing worth noting, we've been shipping updates about every 4 weeks from the beginning of the Firefox product's life. They were noisy and asked you to restart Firefox and prompted with UAC dialogs, and showed a progress meter when you were started. There's nothing new about all of that. We're probably showing that stuff less often now that we're on 6 weeks cycles and not 4 week cycles. We've also turned off the restart prompt for most users and the "What's New" tab for all users.

So, what's different now is that add-ons must move faster to keep up because we're not just shipping security and stability updates frequently, but actual feature updates that can break add-ons. Our big problem is not the noisy updates, but the add-on incompatibility. We're hard at work on that but it's a tough problem.

As you said some of the issues have been fixed already - and hopefully we can put all this in the past soon - but.

Whereas Firefox still gains users, it doesn't gain them as fast as the competitors and it seems to me that it is due to the bad press (even if from uninformed users, or from Google 'evangelists'). The bad press mainly came from the update issues, even thus some are gone now. That's the point I was raising.
