Firefox 5 Coming On June 21

Mozilla has further detailed its new development model for Firefox. The current draft says Firefox 5 will arrive on June 21, 2011 and Firefox 6 will be released on August 18, 2011. All changes to Firefox source code are initially integrated in the mozilla-central Mercurial repository.

Firefox 5 Coming on June

At scheduled intervals (typically 6 weeks), the changes are imported from mozilla-central to one of three other channels (larger features and projects are usually initially developed in other repositories which track mozilla-central). In addition to mozilla-central (currently referred to as nightly), there will also be firefox-experimental, firefox-beta, and Firefox (release), each backed by its own Mercurial repository. These names are currently placeholders and Mozilla may still change them.
