Although Mozilla is still readying Firefox 4 for its official release, the organization is already laying out its plans for subsequent versions of the open source Web browser. In a roadmap published earlier this year, Mozilla revealed plans to issue three more major releases during 2011--bringing the browser's version number up to seven.
As we discussed in our coverage of the roadmap, Mozilla's plan is ambitious and will require a dramatic overhaul of the Firefox development process. Mozillaâ€”which has historically had lengthy development cycles and protracted beta testingâ€”will have to transition to a faster and less-conservative approach to release management. The organization has authored a document that describes how such a transition could potentially be achieved.
