Performance was the main selling point of Firefox 4, so I'm at a bit of a loss as to how you can claim that Mozilla doesn't focus on performance.

There is a big difference between saying you focus on something and actually achieving it. I'm not trying to slam the Firefox team, but they have a lot of strong competition in the performance department these days.

  Yup, we do (I work for Mozilla). We're glad that have this strong competition, it makes for a better market and better products for the users to choose from. Note that Firefox nightlies are already ~10% faster than Firefox 4. Performance continues to be an important part of our development efforts.

    What does 10% faster mean? When people talk about "performance" I'm sure that most of them actually mean UI responsiveness, not raw number crunching performance. How do you measure that and what does 10% in that context mean?

      It's actually around 10% faster at a bunch of things. :) This includes some DOM APIs and just raw JS perf, depending on your platform. Responsiveness will be improved in a different manner. We are working on a bunch of improvements for later in 2011 that should make a big difference. I think Firefox 4 is in general much better than 3.6, and I expect to see parallelism, responsiveness, and reliability continue to improve. The big ticket items are multiprocess browsing and better debugging APIs--we have an issue with developer extensions causing performance problems. This is not necessarily the fault of Firebug or any of the other extensions. We need a better foundation for them to build on, and it really hurts us to give developers a slow experience.

Because it was "the main selling point", I had high hopes. But after using FF4 for a couple months, it hasn't fixed the annoying lags that creep into simple operations (even scrolling!) once you have a lot of tabs open, and require a browser restart for (temporary) relief.
