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.
根据我的研究，该错误消息仅在 Internet 中呈现页面为空白时由 FireFox 生成。出于某种原因，.NET 在创建空页面时会生成“application/xml”响应类型。Firefox 将文件解析为 XML 并没有找到根元素，并吐出错误消息。
in other words, this is a known Firefox issue
换句话说，这是一个已知的 Firefox 问题

I fixed this in my app by setting the Content-Typeheader on the server to text/plain. Like this in Node:
我通过将Content-Type服务器上的标头设置为text/plain. 在 Node 中是这样的：
res.setHeader('Content-Type', 'text/plain');
Use whatever MIME type is appropriate for your data, ie application/json, etc.
使用适合您的数据的任何 MIME 类型，即application/json等。

This can happen too, if you have a [ValidateAntiForgeryToken] attribute on your controller action and try to submit the form without an actual token. You can render the token explicitly with
如果您的控制器操作具有 [ValidateAntiForgeryToken] 属性并尝试在没有实际令牌的情况下提交表单，则也可能发生这种情况。您可以使用显式呈现令牌
@Html.AntiForgeryToken()
which is the preferred solution or remove the validation attribute.
这是首选解决方案或删除验证属性。
