javascript - Disable select, copy and paste of the content of HTML pages in Mozilla Firefox

Question

I want to disable select, copy and paste of the content of HTML pages in Mozilla Firefox. I have used jQuery and JavaScript to disable right-click and copy, select, paste of the contents of HTML pages and it's working fine in IE and Chrome, but not working properly in Mozilla Firefox.

Can we disable copy, paste option in Mozilla Firefox? Any suggestions?

Just copy and Paste the below javascript in your webpage:

<script language="javascript" type="text/javascript"> 
      function disableselect(e) {             
          return false 
      } 
      function reEnable() { 
          return true 
      } 

      document.onselectstart = new Function("return false") 

      if (window.sidebar) { 
          document.onmousedown = disableselect                    // for mozilla           
          document.onclick = reEnable 
      } 

      function clickIE() { 
          if (document.all) { 
              (message); 
              return false; 
          } 
      } 


      document.oncontextmenu = new Function("return false") 

      var element = document.getElementById('tbl'); 

      element.onmousedown = function () { return false; }        // For Mozilla Browser

   </script>

Note:If the above code not works for Firefox then add style="-moz-user-select:none" in the body tag which needs to be restricted alongwith the above code.
