Summary: XMLHttpRequests for web content (and WebExtensions) will now follow the spec and return a null response/responseXML in the event of a parsing error, rather than a document with a <parsererror> root. The web console will also log a more informative error. Non-WebExtension addons and other chrome code will continue to generate <parsererror> documents, for backwards compatibility.
Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=289714 Standard: https://xhr.spec.whatwg.org/#document-response Platform coverage: all. Estimated release: Firefox 50. Devtools bug: none needed. Other browsers: Chrome, Safari and Edge already follow the spec behavior. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
