Comment:

 ok, I've found it! Now I need you developers to find the right solution:
 [[BR]]
 it's in the /wp-admin/js/customize-controls.js line 363-373:

 {{{
 // Check for a signature in the request.
 index = response.lastIndexOf( signature );
 if ( -1 === index || index < response.lastIndexOf('</html>') ) {
         deferred.rejectWith( self, [ 'unsigned' ] );
         //return;
 }

 // Strip the signature from the request.
 response = response.slice( 0, index ) + response.slice( index +
 signature.length );

 // Create the iframe and inject the html content.
 self.iframe = $('<iframe />').appendTo( self.container );

 }}}
 You see, I've commented out the return because then it works in all
 mentioned browsers. I checked the signature variable, it's undefined, but
 I didn't had the time yet to figure out why and where it would be defined.
 This is the return that stops the customizer preview from displaying and
 just stops processing without errors.
