Firefox has merged initial support for Vulkan Video decoding, giving the browser a more cross-platform path for GPU-accelerated video playback beyond Linux's long-running reliance on VA-API. Phoronix reports: Firefox on Linux has long been focused on the Video Acceleration API (VA-API) that isn't universally supported by Linux graphics drivers. This has left to efforts like NVIDIA-VAAPI-Driver to layer VA-API atop NVIDIA NVDEC interfaces to enjoy GPU-accelerated video playback in Firefox. Smaller Arm/embedded graphics drivers also have been largely left out of the game in the VA-API space. But with Vulkan Video we are beginning to see more adoption and in a cross-platform manner. [...] The Firefox 153 release due out in July will have Vulkan Video decoding support available. The Vulkan Video activity in Firefox Git culminated this week with the work of NVIDIA engineer Tymur Boiko and Red Hat's Martin Stransky. Firefox 153.0 is expected for release on 21 July with this Vulkan Video support assuming no last minute issues.

The Web Serial API lets websites write to (and read from) serial devices using JavaScript, including USB and Bluetooth devices with virtual serial ports. And this week's Firefox 151 release introduced support for the Web Serial API on desktop. "Most folks won't use this API," acknowledges Mozilla's blog, "but for our community of builders and tinkerers, it unlocks the ability to use Firefox to communicate directly with compatible hardware devices like microcontrollers, development boards, and other serial-connected devices..." With Firefox's browser engine, Gecko, now supporting Web Serial, users can now connect, code, configure, and control compatible hardware directly from the browser in many workflows, often without additional software or complicated setup... As part of this week's launch, Adafruit, one of the internet's most beloved open-source hardware communities, is collaborating with us to test and validate what browser-based hardware development can look like in Firefox with Web Serial support... With Web Serial support in Firefox 151, Adafruit's browser-based hardware workflows now work directly in Firefox as well, with no additional software or complicated setup required for many projects. We invite you to give it a try... We want the web to be open, flexible, and shaped by the diversity of people building on it. If you're wiring up your first board, experimenting with hardware projects, or dusting off an old electronics kit, give Adafruit and Web Serial in Firefox a try. Build something amazing. Make something useful. Tell us what works. Tell us what breaks. Most of all, make it your own. Mozilla's "Hacks" blog demonstrates with an Adafruit ESP32-S2 based board "where messages sent from web code can be directly displayed on the device over Web Serial." And Mozilla engineer Alex Franchuk even built a handheld device that changes a web page's CSS properties.
