A great collective gasp issued from tuned-in Firefox fans when Mozilla announced that it was switching to a Chrome-like release schedule for its browser. Now Mozilla wants to take things one step further and remove Firefox version numbers entirely from the user-facing parts of the browser, anyway.
You can see the Bugzilla entry for this change, and keep up on Mozilla’s reasoning and discussion through a thread on the mozilla.dev.usability newsgroup. Mozilla’s Asa Dotzler explained, “We’re moving to a more Web-like convention where it’s simply not important what version you’re using as long as it’s the latest version. … The most important thing is confidence that they’re on the latest release. That’s what the About dialog will give them.”
