Not sure what this is or why it happens however there seems to be a bug with Firefox 44/NetScaler when trying to save changes to the configuration. It happened to me when trying to save an edited Session Policy.
Other versions of Firefox and Internet Explorer confirmed working.
Invalid format: Possible encoding values in Accept header can be xml or json only.
This issue has since been resolved in build 65.31/65.35F.
