Hsl color issue in Firefox

I am trying to declare a div border using hsl () like this:

border: 2px solid hsl(0,200,105);

      

        
        
        
      

    

I am using Firefox 3.5 and no border is displayed at all. The same code works fine if hsl () is replaced with rgb ()

I read somewhere that Firefox supports hsl () and hsla ()

Am I doing something wrong?

and if hsl () is not supported, does anyone have some code to convert hsl to rgb?
