Your browser is apparently running an add-on that injects scripts into loaded pages and these scripts cause problems with IE11 (and 10). You can configure Visual Studio to run IE in safe mode by adding an iexplore -extoff entry to the Browse With list and setting it as default as explained here. That said I would recommend investigating which add-on is responsible for this situation as it may have other adverse effects to your web usage (and to your privacy) and you may want to remove it if at all possible.
