I’m use ASP.NET MVC end I take this error only in FF. Why I take this error message? What is the cause of this?
I Don’t understand where the source of this error. Anyone have any thoughts?

Based on my research, the error message is only generated by FireFox
when the render page is blank in Internet. For some reason, .NET
generates a response type of “application/xml” when it creates an
empty page. Firefox parses the file as XML and finding no root
element, spits out the error message.
in other words, this is a known Firefox issue
