SharedArray support in Firefox

[Larry Kosher]

Hello.
It seems that the support has been reenabled in Firefox for SharedArrayBuffer:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBufferHowever my project still throws an error when I try to run it in the latest Mozilla browser. Is there a workaround?
Best regards,
Larry

What is the error?

If it's COOP/COEP-related, then you need to set up your webserver properly,

https://web.dev/coop-coep/

Here is how the test suite does it:

https://github.com/emscripten-core/emscripten/blob/a85b3038738e8f027cf4acad6e272e8c3321ce3f/tests/runner.py#L1370

Btw, does anybody know if the same can be achieved without manipulating the web server? Maybe through some HTML head element? There are many hosting solution which don't allow changing the response headers (e.g. github pages), and even if the hosting solution isn't under external control, it's still not usually under control of the 'product team' (maybe a different department in the same company, maybe an external publishing partner, maybe a separate CDN provider in front of the web server).

IMHO this will be such a PITA that I realldy don't know if it makes sense depending on WASM features which require specific response headers to work.

As far as I remember from reading up on it, there is no in-HTML equivalent; you are simply required to have control over the HTTP(S) server in order to do threading.

Note that <meta http-equiv> is not a general-purpose header substitution system, but a shortlist of several specific features that can be specified which doesn't include arbitrary new HTTP headers: https://html.spec.whatwg.org/multipage/semantics.html#pragma-directives
