elements. For more information on using these values withfill

properties, see the<marker>
documentation (Firefox bug 752638).
HTTP
-
The HTTP
Authorization
header is removed from cross origin redirects. See Firefox bug 1802086 for more details.
APIs
-
Origin private file system (OPFS) is now supported when using the File System Access API.
The data in this file system is origin-specific: permission prompts are not required to access files, and clearing data for the site/origin deletes the storage.
The OPFS is accessed with the
StorageManager.getDirectory()
method, by callingnavigator.storage.getDirectory()
in a worker or the main thread. See Firefox bug 1785123 for more details. -
The HTTP
Authorization
header is removed fromfetch()
andXMLHttpRequest
requests that are redirected cross-origin (fetch()
headers may be added by developers using theoption.headers
argument). See Firefox bug 1802086 for more details.
DOM
- The
FormData
constructor now accepts a second optionalsubmitter
parameter to specify a submit button. If the button has a name or is an image button, it will contribute to the form data set. This makes it possible to create aFormData
object with the same data set as a vanilla form submission triggered by the button. See Firefox bug 1812696 for more details.
Media, WebRTC, and Web Audio
-
RTCInboundRtpStreamStats.trackIdentifier
is now supported. This allows developers to associateinbound-rtp
statistics with a particular track when usingRTCPeerConnection.getStats()
. (For more information see Firefox bug 1804676.)
WebDriver conformance (WebDriver BiDi, Marionette)
WebDriver BiDi
- Changed the behaviors for handling stale elements checks based on recently updated WebDriver classic specification. See Firefox bug 1808894 for more details.

WebDriver:ExecuteScript
causes acyclic object value
error. See Firefox bug 1764594 for more details.
