Mozilla is now distributing a version of Firefox that uses Bing as the default search provider instead of Google. Rest assured that this is a joint project, though: the creatively-named Firefox with Bing website is run by Microsoft, and both Mozilla and MS are clear that this is a joint venture. Now, don't get too excited — the default version of Firefox available from Mozilla.com is still backed by Google, and there's no mention of an alternative, Bingy download anywhere on the site — but it's worth noting that Mozilla has been testing Bing's capabilities using Test Pilot over the last couple of months, and the release of Firefox with Bing indicates that Mozilla is now confident in Bing's ability to provide a top-notch service to Firefox users. Mozilla might be readying a large-scale switch to Bing when its current contract with Google expires in November.
