The roadmap targets 1.0 release for September 14th (one week before FC3T3) : http://www.mozilla.org/projects/firefox/roadmap.html
FC3 for October 18th
Since Evolution is the default mail client, perhaps it's time to push FireFox in Fedora Core and set it as default browser.
I don't see what Evolution has to do with Firefox (nit, the F in Fox is not capitalized).
Or it's better to wait FireFox 1.0 _and_ Thunderbird 1.0.
How so? That mindset sort of implies an application suite. Which is precisely what Firefox and Thunderbird are striving to get away from.
