Intent to ship: WebGPU on Windows
Auto-discovered
Visit resource ↗Description
This is a Mozilla dev-platform mailing-list Intent to Ship post by Jim Blandy announcing that WebGPU will ride the trains to release in Firefox 141 on Windows, with other platforms to follow.
It summarizes Nightly enablement since April 2023, Early Beta on Windows in Firefox 140, W3C WebGPU and WGSL specs, GPU for the Web working group context, planned coverage across Windows, macOS, Linux, and Android, and adapter availability limits on weak GPUs. It notes improving standards compliance, lack of DevTools support at the time, Chrome already shipping, Safari expected later, Conformance Test Suite use in CI, demos, and the Graphics: WebGPU bug component.
It is for browser engineers, WebGPU application authors, and graphics programmers tracking Firefox platform readiness. Familiarity with WebGPU concepts and Mozilla release trains helps.
Access is a public Google Groups thread under mozilla.org's dev-platform list; the linked message is the primary Intent to Ship note with a short follow-up correcting WPT status.
It is useful as a dated primary source for when Firefox committed to shipping WebGPU on Windows and what caveats Mozilla listed.
