The message, verbatim, reads: "We recommend the following browsers: Internet Explorer 6 or 7 and FireFox 2.x on Windows XP SP2, Internet Explorer 7 and FireFox 2.x on Windows Vista, FireFox 2.x on Mac OS X v10.4 Tiger".

The result was a warning page telling that our browser and OS combination was unsupported - as a result of the browser user-agent sniffing by Microsoft's servers - but what really caught our attention was the recommended browsers: IE 6 or 7 - predictably- but Firefox 2.0 as the second option, both on Windows and on Mac OS X. While testing the Flash plug-in for Linux and the very nice Preferences Toolbar we decided to switch to the IE 5.0 for Macintosh user-agent on Microsoft's MSN Video web page. Microsoft killed its proprietary IE engine for Mac OS X and removed it from the firms' download pages in early 2006, suggesting at the time that "Macintosh users migrate to more recent web browsing technologies such as Apple's Safari."
