For those of you who are "nightly" beta testers of Firefox, you might've noticed Minefield has updated today, from version 4.2 to 6.0, and renamed to "Nightly" with a new logo.
If not, then I can tell you that there's probably not going to be a Firefox 5 for whatever reason, 'cuz this is Firefox 6.
The question is, why did they skip Firefox 5, or will Firefox 5 still be version 6.0?
