How to perform arbitrary commands file URIs via ECMAScript in FF, as a user?

In the standard browser chrome, this is rendered as a file: schema-prefixed URI.

@guest271314, you’d put me on the correct track! I’ve ascertained the solution for google-chrome-canary-136.0.7076.0-1.x86_64, too! One merely needs to invoke the console in a verbatim “file://” URI for it to not be cross-origin!

Is this what you meant? Irrespective, thank you for the assistance!
