I can't wait for it to come out. About it's nickname, however, 'Jaunty Jackalope' is a little hard on the ears. I didn't know that a jackalope was an animal, and apparently even Firefox's spell-check didn't know, but whatever. I really like the new notification system and the community themes.
Lately, the stats on my on website and a lot of other websites I know of reflect a much larger percentage of users using Firefox as opposed to IE. I like the way this is going. Maybe Windows -> Linux is going to be next?
I really don't have much more to say. Can't wait for March to end.
