M$ user agents strings and the others

Source (modified)

What did this study conclude?

  • First, lots of users are not running the most up-to-date and secure versions of their Web browsers.
  • Second, this is primarily a phenomenon of Internet Explorer users;
But note that the build data and Gecko version on Firefox give you a lot more version information about Firefox than you get about Internet Explorer. For IE, all you get is major version information, i.e. IE5, IE6, IE7, IE8. The study authors note this themselves:
The USER-AGENT header fields for Firefox, Safari, and Opera contain both major and minor version information, whereas Internet Explorer only contains the major version. Therefore, it was not possible to enumerate the patch level of Microsoft Internet Explorer using this method beyond its major release numbers.
After (in this case flock1.2)
