Webgpu on firefox

I am on the latest firefox for linux: 115.0.2 (64-bit) (NOTE: Same issue on Firefox 116.0b5 (64-bit))

I enabled webgpu using about:config like so:

config

Yet, when running an example, the browser reports no support:

error

Why doesn't firefox let me run webgpu code?

$ inxi -G

Update

Same issue on chromium:

And chromium even states that it has WEBGPU enabled:

Exactly the same issue OP has on OSX 14.4.1 on an M1 laptop and Firefox 125.0.2, release build (installed from HomeBrew)...

I get that it's only enabled by default on nightly builds, but release builds should work after dom.webgpu.enabled is flipped?

Got a bit disappointed when trying to run this demo and realising that flipping that about:config flag has no effect:

I'm not sure what could be the problem with Chrome, because in Chrome 113+ WebGPU is enabled by default and it works for me. Maybe some sort of Linux/driver-specific problem? However, the problem with Firefox is exactly what the error message says:

WebGPU is not yet available in Release or Beta builds.

You have to use the Nightly build. Note, that even in the Nightly build WebGPU is not fully supported.
