title: Why isn't `cursor:context-menu` supported by safari, chrome, or firefox on windows? But it is by IE9 and Opera?
body: <p><a href="http://www.browsersupport.net/CSS/cursor%3acontext-menu" rel="nofollow">This page</a> says that IE9 and Opera 11.6 support the context-menu cursor on Windows, but I know Chrome, Safari and Firefox do not support the context-menu cursor on Windows, it just shows the regular arrow in those browsers.</p>
  
  <p>I simply cannot understand why they wouldn't support that cursor. It would be immensely useful, especially when it's supported in those browsers on Mac.</p>
  
  <p>It's purpose is for when you want the user to know that you've placed a special function on an element that will be activated when you engage the context-menu trigger over that element. For windows, that's a right-click. (most likely to bring up a custom context-menu)</p>
  
  <p>Obviously, everything has a context menu on the web, you can right click anywhere on a page and the generic context menu will appear. This cursor though, is meant for when you place your own special function on an element that will be activated by right-click(and whatever Macs have - a context-menu key?)</p>
  
  <p>Does anyone know why this isn't supported on Windows by those three browsers, but it is on Mac in those three browsers?</p>
