Firefox 4.0 beta 1 is not released yet, but it probably will be within a few days. (There was a candidate build yesterday, but we decided to wait for a second build with some more fixes.) When it is actually released, it will be announced on http://blog.mozilla.com and available from http://mozilla.com/firefox/all-beta.html

For now you can download the latest nightly "Minefield" build from http://nightly.mozilla.org/

See https://wiki.mozilla.org/Releases/Firefox_4.0b1 to track progress of the release.
