The person most individually responsible for Mozilla's culture would be Mitchell, not whoever happens to be CEO of the Mozilla Corporation right this second. For example at various organization-wide events (all-hands, summits) Mitchell is the one giving the "where are we going and what are the goals?" talk. She's also the one to whom non-technical project governance issues ultimately escalate. The fact that there is a complicated interaction here between the corporate structure and the project structure is a bit confusing; it's not a common setup. But in practice the CEO doesn't have much impact on the culture of the project, from what I've seen.
