the time see these errors when click on link or button causes page reload or navigate different page, page refresh causes errors - disappear page begins loading.

something related ajax? seems such stupid post, can't see wrong in code.

update:

there posts on question infer there problem content or markup. since happening on every page, went _layout.cshtml , step step removed sections of code, yet problem still occurs.

its not problem code, new feature in vs 2013 phone call browser link. can disable unchecking enable browser link in next image:

i haven't used much, more info browser link , uses, next msdn blog covers pretty well.

edit

the blog linked rtm version of vs 2013, here article asp.net provides little more info past rtm version.
