bookmarking window in background

In your bookmarklet you need to do a window focus via setTimeout to bring the new window to the foreground, like this:

javascript:var es=['body','frameset','head'];var u=document.location.protocol+'//www.soup.io/';var fn='soup_bookmarklet_'+(Math.floor(Math.random()*100000));w=window.open(u+'bookmarklet-loading.html',fn,'toolbar=0,resizable=1,scrollbars=yes,status=1,width=450,height=400');
setTimeout('w.focus()',50);
try{var s=document.createElement('script');s.setAttribute('src',u+'bookmarklet/js/'+fn+'/5');for(var i=0;i<es>);}void(0);
