I installed Firefox2 Beta2 on my iBook a short while ago.. and was greeted with this!
Google is Evil! Firefox Google Confirms it! ;-)

Update: The URL which triggers the false positive is http://www.google.co.in/firefox?client=firefox-a&rls=org.mozilla:en-US:official
Update2: Came to know from #firefox that the blacklist actually is generated by Google!
