yourbrowsermatters.orgは安全ですか？

This domain name and hosting is owned by Microsoft Corporation, author and vendor of Microsoft Windows Internet Explorer (formerly known as Microsoft Internet Explorer), the Web browser routinely criticized for bringing up the rear in Web security and Web usability, and routinely used by Microsoft to extend its operating system monopoly into monopolization of other software markets. The only purpose of this domain name is to spread unwarranted fear, uncertainty, and doubt ("FUD") about non-Microsoft products, including those offered for free or as open source, a clearly unethical conflict of interest for Microsoft Corporation.

This site is a Microsoft bullshit. It doesn't "test" anything nor your browser. It only shows the known features of browser without concern of installed add-ons. It is made to favour MS IE 9 instead of other browser, don't believe this site. (and sorry for my bad english ;))
