Developer tools
- You can now inspect server-sent events using the Network Monitor (bug 1640857).
- The Network Monitor's Message panel has now been merged with the Response panel — messages (e.g. from WebSockets or server-sent events) can now be viewed right below the responses list (bug 1636421).
HTML
- The color picker used for
<input type='color'>
is now keyboard-accessible on Windows (bug 1526820). - The
allow-downloads
flag for the<iframe sandbox>
attribute is now supported (bug 1656212).
CSS
- Support for the new
::file-selector-button
pseudo-element has been added. This pseudo-element represents the file selection button inside an<input type='file'>
element (bug 1635675, bug 1662478). - We have improved error recovery for the
:is()
and:where()
pseudo-classes. These pseudo-classes now accept a forgiving selector list, where an invalid selector in the list will not render the entire list invalid (bug 1664718). appearance: button
now applies only to buttons; thebutton
value ofappearance
will otherwise behave asauto
(bug 1662703).
Removals
- We have removed the proprietary
:-moz-user-disabled
pseudo-class (bug 1664432).
HTTP
- The
Content-Disposition
header'sinline
directive will now be ignored if the HTML<a>
element'sdownload
attribute is specified (for same-origin URLs). Note that if specified theContent-Disposition
headerfilename
will be used in preference to a filename specified in thedownload
attribute (bug 1658877).
APIs
New APIs
Tabs For Android
- The Media Session API is now enabled by default (bug 1665496).
DOM
Document.execCommand()
is no longer supported for nested/recursive calls, which will now returnfalse
(bug 1634262).Element.setPointerCapture()
throws theNotFoundError
exception if the pointerid
is invalid, as per the specification (bug 1662124). Previously it wrongly threw anInvalidPointerId
exception.- The
window.name
property is reset to an empty string if a tab loads a page from a different domain, and restored if the original page is reloaded (e.g. via the 'back' button). This prevents an untrusted page from accessing any information that the previous page might have stored in the variable. This change may impact frameworks that usewindow.name
for cross-domain messaging (bug 444222).
WebDriver conformance (Marionette)
- To simulate a more realistic user navigation, all supported navigation commands have been moved to the parent process (bug 1612831).
- We updated the checks for the current or top-level browsing context for all the commands to improve conformance with the WebDriver specification (bug 1493108).
- Fixed a bug in
WebDriver:ElementClick
that sometimes caused the command to return before the click event was actually synthesized (bug 1394354).
Changes for add-on developers
- The
tabs.captureTab()
andtabs.captureVisibleTab()
methods now capture an area of the relevant tab's content specified by therect
property of the providedoptions
object, or the visible area of the tab if this property is not provided (bug 1636508). Previously therect
property was not available, and these methods always captured the visible area of the relevant tab
