Useragent guesser

Your browser claims to be: CCBot/1.0 (+http://www.commoncrawl.org/bot.html)
Probably your browser is: the Googlebot?

detectable browsers

Its very simple to fake the useragent of mozilla firefox:

But the detection says:

Your browser claims to be: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)
Probably your browser is: a Mozilla browser

How does it work?

Every browser has its own set of default-headers, which are sent with every request.
i.e. your browser has sent these headers:

accept:          text/html,application/xhtml+xml,text/xml;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
accept_charset:  ISO-8859-1,utf-8;q=0.7,*;q=0.7
accept_encoding: gzip

just try it with another browser, and compare the headers.

How to protect yourself

The best way to protect your privacy is to use a proxy, which hides more than the useragent string, or even uses its own headers for the request.
With Mozilla (Firefox) you can try to change the headers, but keep in mind, that this will also affect your browsing experience:
