I'm working on a site that has a custom "coda slider" type navigation. Basically all "pages" are on a horizontal line and there's a frame so you only see one at a time. I have "< Prev" and "Next >" buttons on the bottom and when you click them, they slide the horiz line over to the right spot. So the Prev/Next buttons have dynamic click handlers. My horiz frames scroll very smoothly in Chrome and IE7 (ha) but they're grindingly messed up in Firefox. By grindingly messed up, I mean they barely show any motion at all. I'm not sure if this has to do with my click event handlers or not. Here's my code to bind the clicks:

jQuery(".NextBtn").click(function(){
      
   if(pos < (cellCount-1)){
      curLeft = curLeft - cellWidth;
      jQuery(".CellList").animate({left: curLeft + "px"}, 500 );
      pos++;
   }
   
   //check hover box status
   showHideHoverBox();
   return false;
});

jQuery(".PrevBtn").click(function(){
   if(pos > 0){
      curLeft = curLeft - (-cellWidth);
      jQuery(".CellList").animate({left: curLeft + "px"}, 500 );
      pos--;
   }
   
   //check hover box status
   showHideHoverBox();
   
   return false;
});


Do I need to unbind anything first? I have other click bindings elsewhere for other stuff too. Could that be causing any problems?
