FIREFOX cursor loss problem. _html/css_WEB-ITnose

firefox ，光标

 var selection = this.ifr.contentWindow.getSelection();
        var range;
        if (selection) {
            range = selection.getRangeAt(0) ;
         } else { 🎜> oLastNode = oFragment.lastChild; / / Used to correct the position of the editing cursor
Range.insertNode(oFragment);
range.setEndAfter(oLastNode); //Place the editing cursor after we insert the content
Range.setStartAfter(oLastNode);
selection.removeAllRanges(); //Clear all selections, otherwise the content we inserted and the text just now are selected
selection.addRange(range); //Insert content
this.edc.body. focus();
Is there anything wrong with this code? Why do icons disappear in Firefox? I beg God to tell me the reason.
