According to spreadfirefox.com, a year ago today was the release of Mozilla Firefox 1.0

Firefox was released prior to November 9th, 2004 in preview releases and early betas, but the official 1.0 came out a year ago today, hard to believe. According to some sources it has as much as 10% of the web market share, although that's tough to gauge (varies by site content.) It shipped originally with support for "17 languages and on 5 platforms".

It looks as though now, we're on the verge of the 1.5 release of Firefox, 40 languages will be supported as well as some great improvements. It's hard to believe that just one year has passed, is 20% possible by next November? 15%? Will Opera continue to pick up market share as well now that it's ad-free? Interesting things can happen in just a year.
