This post discusses the future of WebGPU, especially in light of recent changes involving Mozilla and its relationship with Google.
Historically, Google paid Mozilla (the developers of Firefox) roughly 80% of its annual revenue for making Google the default search engine, as noted on Wikipedia. However, beginning this year, that revenue stream will end. Mozilla’s position has been shaky for some years, and Firefox’s development pace has been slow.
For context, WebGPU is the next-generation graphics API for browsers, and three.js is making a transition toward supporting it, as seen in their example.
To fully benefit from the new WebGPU features, support across all major browsers is necessary. Currently, Chrome ships with WebGPU support, but Firefox still hasn’t fully implemented the spec (see the implementation status), nor rolled it out to its main release.
The image below shows Firefox’s beta ('Nightly') status, which indicates that these features are still in early testing phases.
My concern is that with Mozilla’s declining revenue and sluggish development, Firefox might become irrelevant, and as developers and users of three.js, we may lose access to WebGPU features on this platform. Does anyone have insights on whether Firefox’s WebGPU support is still on track, or what the long-term outlook for Firefox might be?

WebGPU Support in Firefox and Mozilla's Future
Based on the information provided, there are legitimate concerns about the future of WebGPU support in Firefox given Mozilla's current situation:
-
Financial challenges: With Google ending its search engine deal that previously provided approximately 80% of Mozilla's revenue, Mozilla faces significant financial pressure.
-
Current WebGPU implementation status: Firefox has not fully implemented the WebGPU specification yet, while Chrome has already shipped with WebGPU support. The implementation is still in early testing phases in Firefox Nightly builds.
-
Development pace: Firefox's development has been described as slow, which could further delay full WebGPU implementation.
This situation creates uncertainty for three.js developers who are transitioning to WebGPU and need cross-browser support to fully leverage its features.
Without additional information about Mozilla's current development priorities or alternative funding sources, it's difficult to provide a definitive answer about whether Firefox's WebGPU support is still on track or what the long-term outlook for Firefox might be.
For developers concerned about this situation, it would be prudent to:
- Monitor the implementation status on the GitHub wiki you referenced
- Follow Mozilla's technical roadmaps and announcements
- Consider fallback rendering options in three.js projects that require broad browser compatibility
The situation highlights the challenges of web standards adoption when browser vendors face different constraints and priorities.
