I've interpreted the title that way, too, but partly because it might actually make sense.

Consider this. Firefox peaked a while ago; since then, Chrome ate every other browser's lunch, and the only browser that had user share declining faster than Firefox was IE (but even so, IE still has more users). Google has the brand recognition on their side, and on top of that, they have actually made a browser that "just works" for 99% of people out there, the way Firefox never quite did.

Since contesting Chrome's market share is rather pointless, Firefox needs a niche of its own now. Integrating Tor in a seamless way would be a great opportunity to create one.
