Cambios para desarrolladores Web

HTML

CSS

  • Esquinas con estilos punteados y rayados (dashed, dotted) Border-radiused ahora son mostradas con el estilo especificado en lugar de estilo sólido (bug 382721).
  • El selector pseudo-clase no estándar :-moz-full-screen-ancestor fue removido (bug 1199529).
  • box-sizing: padding-box fue removido, dado que ya no forma parte de la especificación y Firefox era el unico entre los principales navegadores que lo implementaba (bug 1166728).
  • Se removió el prefijo de los tres valores isolate, isolate-override, y plaintext de la propiedad unicode-bidi (bug 1141895).
  • En modo de compatibilidad, la etiqueta de un elemento de lista ahora hereda el tamaño de la lista, como en el modo estandar (bug 648331).
  • Las pseudo-clases :in-range y :out-of-range cambiaron su comportamiento para no coincidir elementos input deshabilitados o de solo lectura (bug 1264157).
  • Se removió el prefijo de la pseudo-clase :any-link(bug 843579).
  • El valor space para border-image-repeat fue implementado (bug 720531).

JavaScript

Herramientas de desarrollador

  • El panel de Modelo de caja fue movido al panel lateral Computado (bug 1247729).

HTTP

Seguridad

Redes

DOM

SVG

  • The allowReorder attribute has been dropped and the behavior it was setting is now the default for SVG <switch> elements (bug 1279690).
  • The defer keyword for the preserveAspectRatio attribute on SVG <image> elements has been removed to follow the latest SVG2 specification (bug 1280425).

Drag and Drop API

Pointer Lock API

  • The Pointer Lock API is now unprefixed (bug 991899).
  • Before Firefox 50, requestPointerLock() asked for permission using a doorhanger, and pointer lock would not be enabled until the user granted permission. From Firefox 50, pointer lock is like the fullscreen API: it's granted immediately, but a notification is displayed explaining to the user how to exit (bug 1273351).

IndexedDB

Service Workers

  • The WindowClient.navigate() method has been implemented. This method lets you open a specified URL into a client window which is being controlled by the service worker (bug 1218148).

WebGL

WebRTC

Web Audio API

Audio/Video

  • The AlignSetting enum (representing possible values for VTTCue.align) incorrectly previously included the value "middle" instead of "center". This has been corrected (bug 1276130).
  • The non-standard and experimental method HTMLMediaElement.seekToNextFrame() now seeks to the next frame in the media asynchronously, rather than synchronously, and returns a Promise which resolves once the seek is complete.
  • The implementation of HTMLTrackElement has been corrected to allow <track> elements to load resources even if not in a document (bug 871747).
