i am trying to download it from yesterday but keep receiving the same message

Safari can’t open the page “http://download.mozilla.org/?product=firefox-3.0.9&os=osx&lang=en-US” because the server unexpectedly dropped the connection, which sometimes occurs when the server is busy. You might be able to open the page later.

the release of firefox 3.5 beta 4 is imminent, i too have problem accessing their server in past 2 days. Its there for sure, if you can't reach the page www.mozilla.com, you can download it from mirror sites such as http://pv-mirror02.mozilla.org/pub/mozilla.org/firefox/releases/3.0.9/mac/en-US/
