Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.3a1pre) Gecko/20091107 Minefield/3.7a1pre

It wants to go the a site called Browser Upgrade but never gets there.
My guess is that it doesn't like my useragent string, so that could be the reason why I'm redirected to that site, but it is not clear why it doesn't send the site but gets in a loop instead. 

This string is accepted: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5

but not the Minefield one. I see no installation BTW.
Do you also have problems with the latest release? http://www.mozilla.com/en-US/
