Firefox 133.0.3 fails with:

Uncaught (in promise) ReferenceError: GPUShaderStage is not defined

nightly with webgpu enabled gets farther, but still fails.

    Uncaptured WebGPU error: Shader module creation failed: Parsing error
    Encountered one or more errors while creating shader module "Update Lights Shader Module"
    WebGPU compilation info for shader module "Update Lights Shader Module" (1 error(s), 0 warning(s), 0 info)

    Shader 'Update Lights Shader Module' parsing error: unknown attribute: 'must_use'

    44 │   @must_use
       │    ^^^^^^^^ unknown attribute
    Uncaptured WebGPU error: ShaderModule with 'Update Lights Shader Module' label is invalid 

looks like this happens for most of the shaders.

edit: seems to be related to this issue https://github.com/gfx-rs/wgpu/issues/5186

WebGPU still isn't enabled in Firefox by default (it's behind the dom.webgpu.enabled flag)

I tried setting the flag to true but I get this after sadly.

Uncaught (in promise) DOMException: WebGPU is not yet available in Release or Beta builds. initialize https://gnikoloff.github.io/webgpu-sponza-demo/assets/index-... <anonymous> https://gnikoloff.github.io/webgpu-sponza-demo/assets/index-... <anonymous> https://gnikoloff.github.io/webgpu-sponza-demo/assets/index-...

Ah, apologies - it does need that config flag, but it's also only available in Nightly builds.
