[Firefox MV3] Any plan to support scripting eval in "sandbox"?

Add-ons Development

In Chrome MV3, there is the sandbox feature that allowing JavaScript eval inside the sandbox page.

    "sandbox": {
        "pages": [
            "src/sandbox.html"
        ]
    },
    "content_security_policy": {
        "sandbox": "sandbox allow-scripts; script-src 'self' 'unsafe-eval'"
    }

However it seems not supported in Firefox.

This is a required feature in extension “ScriptCat” for running the code in background.
I expect that I can append an sandbox iframe in Event Page. The sandbox iframe is isolated from all extension APIs and just allow to communicate with the parent frame, so it can do JavaScript eval safely.

Here is the issue for that:

Thanks for quoting it.

From the Rob Wu’s last reply, it seems just returned to a positive direction. We are looking forwards to it.
