I like Mozilla's new strategy of partnering with popular open source projects, e.g. Tor, now this. It's a good strategy because Mozilla's proprietary competitors, namely Google, might have trouble fully integrating and partnering with open source initiatives. Further, the decision makers of open source projects are presumably far more interested in partnering with Mozilla than Google.

There is a lot of value for Mozilla to extract from open source, and as long as it remains an open source company itself, it will have a "leg up" on its competitors, and a much easier time in negotiations with open source stakeholders. I suspect we'll see more integrations of large, popular open source projects into the Mozilla browser.
