Changes for Web developers

DOM

  • Support for the multipart property on XMLHttpRequest and multipart/x-mixed-replace responses in XMLHttpRequest has been removed. This was a Gecko-only feature that was never standardized. Server-Sent Events, Web Sockets or inspecting responseText from progress events can be used instead.

Changes for add-on and Mozilla developers
