At the moment, they have a technical plan, working on the features and infrastructure that hold Firefox back. For example, they've put a lot of effort into reducing memory foot-print, into optimizing their 2D graphics stack, making it possible to have simple add-ons that work reliably across Firefox upgrades and even small things like "how much screen real-estate is taken up by non-web-content". Once they've paid off some of the technical debt they built up with long-term supported releases, and they have a product that will wow Chrome users, I'm sure you'll hear their marketing department kicking into gear.
