We’ve recognized that Mozilla faces major headwinds in terms of both financial growth and mission impact. While Firefox remains the core of what we do, we also need to take steps to diversify: investing in privacy-respecting advertising to grow new revenue in the near term; developing trustworthy, open source AI to ensure technical and product relevance in the mid term; and creating online fundraising campaigns that will draw a bigger circle of supporters over the long run.
