Your browser has identified itself as:
CCBot/2.0 (http://commoncrawl.org/faq/) via its "User Agent String".
Using the browser's 'User Agent String' is not a great way to determin browser
features for several reasons. First and formost, the string can be forged very
easilly. Therefore it is much safer to detect if a browser supports features you wish
to use. For example, if you intend to use the browser storage feature 'localstorage'
you can test to see if it is supported before using it.
