FWIW, at Figma we're running our extension system through <iframe srcdoc="...extension code here...">. This means our extension developers won't be able to use Firefox if they want to debug their extensions.

To be clear, this is not about Firefox extensions, but rather about the extension system that we're building for the Figma website.

I'm going to close this because I cannot reproduce the NS_ errors. I do however see https://bugzilla.mozilla.org/show_bug.cgi?id=1651543 so I've filed that.

@jonas I unfortunately can't tell exactly what issue here was blocking you for extension work, so if you're still having issues, it would be wonderful if you could file a new bug for that.
