See Firefox bug 1539075 for more details. Reject any violations in requirements or recommendations.įirefox supports JPEG XL images if this feature is enabled. 1 (default): Reject violations of requirements, but allow violations of recommendations.0: Accept images with specification violations in both recommendations ("should" language) and requirements ("shall" language), provided they can be safely or unambiguously interpreted.This allows Firefox users to display images that render on some other browsers, even if they are not strictly compliant. The _strictness preference can be used to control the strictness applied when processing AVIF images. See Firefox bug 1280613 and Firefox bug 778617 for more information. This adds the promise-based methods appendBufferAsync() and removeAsync() for adding and removing media source buffers to the SourceBuffer interface. The following experimental features include those found in the WebRTC API, the Web Audio API, the Media Source Extensions API, the Encrypted Media Extensions API, and the Media Capture and Streams API. See Firefox bug 1602129 for our progress on this API. The WebGPU API provides low-level support for performing computation and graphics rendering using the Graphics Processing Unit (GPU) of the user's device or computer. Currently, there are no WebGL extensions being tested by Firefox. When this preference is enabled, any WebGL extensions currently in "draft" status which are being tested are enabled for use. The hit region API allows you define an area of your canvas and provides another possibility to expose interactive content on a canvas to accessibility tools. Whether the mouse coordinates are within a particular area on the canvas is a common problem to solve. For more information, see Firefox bug 1807685, Firefox bug 1804573, and Firefox bug 1809005. The longhand and shorthand properties are now available behind the preference. When using the scroll-timeline shorthand property, the order of the property values must be scroll-timeline-name followed by scroll-timeline-axis. You can alternatively use the scroll() functional notation with animation-timeline to indicate that a scrollbar axis in an ancestor element will be used for the timeline.įor more information, see Firefox bug 1676791, Firefox bug 1754897, and Firefox bug 1737918. The scroll timeline can then be associated with an animation by setting the animation-timeline property to the name value defined using scroll-timeline-name. The scroll-timeline-name and scroll-timeline-axis properties (and the scroll-timeline shorthand property) allow you to specify that a particular scrollbar in a particular named container can be used as the source for a scroll-driven animation. Earlier called "scroll-linked animations", a scroll-driven animation depends on the scroll position of a scrollbar instead of time or some other dimension.
