伙计们，我的iframe有问题。当我使用chrome时，它工作正常，但是当我使用mozilla时。 i框架卡住了。有人可以知道解决方案吗？

              title="Check Room Test"
              size="modal-extra-lg"
              backdrop="static"
              token="6hsfbuejnbub}etk5ufhbmtbsj">
              <div id="iframe-form-value"></div>
              <!-- Check In -->
              <div class="input-class col-sm-3 col-xs-12">
                  <input type="text" class="col-xs-12" id="check-in" placeholder="CHECK-IN" readonly="readonly">
