Does Firefox for Android 82 support SharedArrayBuffer?

137 views Asked by At

Related with my previous question, next I tried to use SharedArrayBuffer on Firefox for Android 82.

I failed it via both localhost and https server.

Hasn't Firefox for Android 82 supported SharedArrayBuffer yet?

The document says that Firefox for Android supports it since version 79. Then how can I fix it?

Thanks.

The linked MDN article is in Japanese and stale. If you look at the English version, you'll learn that it needs "cross-origin isolation" to enable SharedArrayBuffer.

Cross-origin isolation is very constrained environment, but if you are interested to learn more you may start from here: https://web.dev/coop-coep/
