I want to use SharedArrayBuffer on Firefox. So I let my web server add Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy in response header according to the document .

It works fine when you access the server as localhost, but it does not work when you access the server as its IP address. How can I fix it?

The version of Firefox is 83.0.

Thanks.

I see this question is a few months old now. I have received an email from Google Search Console telling me


    Google systems have recently detected that SharedArrayBuffers (SABs) are used on

my site. However, I have no idea what they are, or how to detect where I am using them on my site. As you mention wanting to use them, would you mind providing any info about what they are please? I have read the Mozilla page about them, but still have no idea how I can be using them on my site, which uses some CDNs and displays some videos using iFrames. Any advice much appreciated. Thanks! – 4532066 Mar 16, 2021 at 16:33 @4532066 san, SABs are mainly used for communications among main thread and web workers. If you use multithread C/C++ program via Emscripten on your site, it may use SABs. – Yuji Mar 16, 2021 at 23:04

It seems that you need HTTPS when not accessing the server by localhost.

It is explained in this link by the following line :

As a baseline requirement, documents will need to be in a secure context.
