According to Stephen Horlander, the new default theme for Firefox is ‘a 0.1 release at best’ (via djst’s nest)

It’s also well worth reading djst’s previous post on the subject, where he goes into more detail about how the Winstripe theme doesn’t work on Windows XP. There are also a good selection of comments on that post, mainly about how when Qute was made the default, lots of people complained about it making Firefox look too much like a Windows app. Frankly, in my mind this is the audience Firefox should be after, and making it look like either less of one, or one with a lame skin is just asking for trouble.
