You are using multiple box shadows so try doing this (also removes alpha from box shadows I have done this below for you to try)

box-shadow: 0px 1px 3px rgba(0,0,0), 
            inset 0px 4px 2px -2px rgba(255,255,255), 
            inset 0px -3px 1px -2px rgba(0,0,0), 
            inset 0px -20px 200px -100px rgba(0,0,0);

-moz-box-shadow: 0px 1px 3px rgba(0,0,0), 
                 inset 0px 4px 2px -2px rgba(255,255,255), 
                 inset 0px -3px 1px -2px rgba(0,0,0), 
                 inset 0px -20px 200px -100px rgba(0,0,0);

-ms-box-shadow: 0px 1px 3px rgba(0,0,0), 
                inset 0px 4px 2px -2px rgba(255,255,255), 
                inset 0px -3px 1px -2px rgba(0,0,0), 
                inset 0px -20px 200px -100px rgba(0,0,0);

-webki-box-shadow: 0px 1px 3px rgba(0,0,0), 
                   inset 0px 4px 2px -2px rgba(255,255,255), 
                   inset 0px -3px 1px -2px rgba(0,0,0), 
                   inset 0px -20px 200px -100px rgba(0,0,0);

If there is still a problem dou you have any fiddle or link for that so I can check properly
