Débogueur

• Vous pouvez maintenant activer/désactiver le blackboxing des groupes et dossiers sources listés dans le volet Liste des sources via les options du menu contextuel (bug 1118152).
• L'option de menu contextuel Copier la trace de la pile d'appels du volet Pile d'éxécution copie désormais les URL complètes, et pas seulement les noms de fichiers (bug 1619039).

Moniteur de réseau

• Dans la liste des requêtes du réseau, vous pouvez maintenant double-cliquer sur un séparateur de colonne pour redimensionner la colonne à gauche de celui-ci afin qu'il corresponde à son contenu (bug 1615102).
• Le menu contextuel de la requête réseau Copier > Copier comme cURL dispose d'une nouvelle option, --globoff, qui supprime la fonction de globbing (correspondance de caractères génériques) du cURL si l'URL copiée comprend des caractères entre crochets (bug 1549773).
• L'onglet Messages du panneau de détails pour les requêtes de socket web a un nouveau filtre - Contrôle - pour afficher les cadres de contrôle, et les filtres sont maintenant regroupés dans une liste de sélection (bug 1566780).

Console web

• In multi-line mode, code snippets longer than five lines are abbreviated to five lines, preceeded 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).

Débogage à distance

• 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.

• 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).

• Firefox now supports CSS4 system colors (bug 1590894).

No changes.

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

Nouvelles APIs

• 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 audioworklet destination for requests. This causes received data to be dispatched to an AudioWorklet (bug 1402784).

Suppressions

• 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).
