Shortly thereafter, Firefox's new channel system will be implemented. Firefox 5a2 will be introduced as the first Aurora build, and we should also see a Firefox 6 Nightly build. While we we're not sure where they came from, one Sören Hentzschel seems to have unearthed the new Nightly and Aurora logos (see above), along with new About Firefox dialogs (after the break).
In other news, if you want to take a sneak peek at the new 'channel changing' technology that will be introduced in upcoming Firefox builds, head to about:config and create a new string called app.update.desiredChannel -- the value doesn't matter. Then open Help > About Firefox and you'll be able to switch channel, but it doesn't do anything just yet (image after the break). Here's hoping that Firefox channel switching is smoother than Chrome.
