More Capable DevToolsįirefox 67 and 68 Developer Edition bring enormous improvements to Firefox’s JavaScript Debugger. You can read more about WebRender in The whole web at maximum FPS: How WebRender gets rid of jank. This marks the first time that WebRender has been enabled outside of Nightly and Beta builds of Firefox, and we hope to expand the supported platforms in future releases. Today, we’re beginning to gradually enable WebRender for users on Windows 10 with qualified hardware. Nearly four years ago we started work on a new rendering architecture for Firefox with the goal of better utilizing modern graphics hardware. Defined in Cascading and Inheritance Level 4, revert is also supported by Safari. The prefers-color-scheme media feature is currently supported in Firefox and Safari, with support in Chrome expected later this year.Īdditionally, the revert keyword is now supported, making it possible to revert one or more CSS property values back to their original values specified by the user agent’s default styles (or by a custom user stylesheet if one is set). As an example of what this looks like in the real world, Bugzilla uses prefers-color-scheme to trigger a brand new dark theme if the user has set that preference. New in Firefox 67, the prefers-color-scheme media feature allows sites to adapt their styles to match a user’s preference for dark or light color schemes, a choice that’s begun to appear in operating systems like Windows, macOS and Android. Firefox 67 is available today, bringing a faster and better JavaScript debugger, support for CSS prefers-color-scheme media queries, and the initial debut of WebRender in stable Firefox.
