internet explorer 9 - Magnific Popup + ajax call for html fragment -

trying implement magnific pop-up ajax content. want load element page link pointing to. make easier i'm using "data-fragment" attribute on links. markup looks this:

<a href="browse-taxonomy.html" class="modal-ajax-fragment" data-fragment="#browse-taxonomy" title="browse"> 

js function looks this:

$( '.modal-ajax-fragment' ).magnificpopup({           type: 'ajax',           fixedcontentpos: false,           fixedbgpos: true,           overflowy: 'auto',           closebtninside: true,           preloader: false,           midclick: true,           removaldelay: 300,           mainclass: 'my-mfp-zoom-in',           disableon: 480,            callbacks: {               parseajax: function( mfpresponse ) {                      var mp = $.magnificpopup.instance,                         t = $( mp.curritem.el[0] ),                         fragment = ( t.data( 'fragment' ) );                          mfpresponse.data = $( mfpresponse.data ).find( fragment );                         console.log( 'ajax content loaded:', mfpresponse );             }           }       }); 

works great in modern browsers (chrome, ff, safari, ie10) -- must doing wrong b/c absolutely chokes in ie9 , below. ie's console/inspector tells me nothing -- work after spinning minutes -- locks program up.

any ideas causing such headaches ie? thanks!

solution: remove line logs mfpresponse console:

// console.log( 'ajax content loaded:', mfpresponse );
