In a bid to restrict the usage of Facebook during office hours, Microsoft Australia's chief security advisor, Stuart Strathdee said that Internet Explorer 6 is being used by many companies.

This according to the security expert is explained as an old technology that is not compatible enough to render advanced websites like Facebook and other social networking websites, making IE6 a popular choice for companies who can impose restriction on banning these sites.

Stuart Strathdee stated, “Companies are happy to stay with IE 6 because ... a lot of the social networking sites and the sites that they deem are unnecessary for work purposes, they're not going to render and function properly within [older versions of] IE.”

It is since the privacy concerns that occurred due to IE6 that led to banning of IE6 and since then Microsoft urges users to upgrade it next version of IE.
