This article provides information about the changes in Firefox 76 that will affect developers. Firefox 76 was released on May 5, 2020.

Changes for web developers

Developer tools

You can now enable/disable blackboxing of source groups and folders listed in the Source list pane via context menu options (bug 1118152).
The Call stack pane's Copy stack trace context menu option now copies full URLs, not just filenames (bug 1619039).

Network monitor

In the network request list, you can now double-click a column divider to resize the column to the left of it to fit its contents (bug 1615102).
The network request Copy > Copy as cURL context menu option has a new option available, --globoff, which suppresses cURL's globbing (wildcard matching) feature if the copied URL includes square bracket characters (bug 1549773).
The Messages tab of the details pane for web socket requests has a new filter — Control — for showing control frames, and the filters are now grouped together into a selection lst (bug 1566780).

Web console

In multi-line mode, code snippets longer than five lines are abbreviated to five lines, preceded by a disclosure triangle (or 'twistie'), and followed by an ellipsis (…). You can click anywhere in this area to show the code, and click again in that area to collapse it (bug 1578212).
DOM element references outputted into the console now have a 'Reveal in inspector' context menu option, which shows the element in the HTML pane of the Page inspector (bug 1612276).

Remote debugging

Because of differences in DevTools versions, it is not possible to debug releases of Firefox for Android that are based on version 68, from desktop Firefox versions 69 or later. When attempting to do this, the Firefox desktop browser will now show a message informing the user of this problem, and offering possible next steps (bug 1625906). See Connection to Firefox for Android 68 for more information.

HTML

The <input> element's min and max attributes now work correctly when the value of min is greater than the value of max for control types whose values are periodic (that is, values that wrap around at some point). This is particularly helpful, for example, with date and time inputs, where you might want to specify a time range of 11 PM to 2 AM (bug 1608010).

CSS

Firefox now supports CSS4 system colors (bug 1590894).

SVG

JavaScript

The numberingSystem and calendar options of the Intl.NumberFormat, Intl.DateTimeFormat, and Intl.RelativeTimeFormat constructors are now enabled by default (bug 1625975).

APIs

Firefox 76 Release Date

New APIs

Firefox 76 Youtube

Firefox now supports audio worklets by default, with support for AudioContext.audioWorklet, which lets you use the AudioWorkletProcessor and AudioWorkletNode interfaces to process audio in real time off the main thread (bug 1616725).

DOM

UI-parts related items in the windowFeatures parameter of window.open() can no longer control the visibility of each UI part separately, but become a condition for whether to open a popup or not (bug 1507375).
Attempts to navigate to an unknown protocol using methods such as location.href or <meta http-equiv='refresh'> are now blocked (see bug 1528305; also see Navigation to unknown protocol will be blocked for more information).
The IntersectionObserver() constructor now accepts a Document object as its root, as well as an Element object (bug 1623623). This lets you explicitly use a window's entire content area as the intersection bounds.
The Fetch API now supports the audioworkletdestination for requests. This causes received data to be dispatched to an AudioWorklet (bug 1402784).

Removals

We've completely removed the Window appinstalled event (and the associated Window.onappinstalled handler property) — these were never shipped, and have now been removed from the Web Manifest spec (bug 1625384).

HTTP

Security

No changes.

Mozilla Firefox 76.0.1

WebDriver conformance (Marionette)

Firefox no longer reports false for navigator.webdriver when used for automation / testing via geckodriver (bug 1632556).
