When the editor crawls a website in order to get content to display in the editor, it has to identify itself to the website so that it can understand how it's being viewed.
For the editor, our user agent as follows;
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:18.104.22.168) Gecko/20100722 Firefox/3.6.8
There are a couple of times when knowing our user agent comes in handy. For example, if you're website is blocking our editor from accessing our site, you can give them our user agent so that they can put it in their white-list.
