    From emf@21:1/5 to All on Tue Jul 19 17:46:50 2022
    Hi.

    I have on my computer a program that reads a local text file. It
    used to work OK but now it doesn't and the Web Developer Tools
    of Firefox says:

    Cross-Origin Request Blocked: The Same Origin Policy disallows
    reading the remote resource at file:///C:/...

    Is there any work-around?

    Thanks,

    Eustace

    No.

    No.

    I wouldn't be as categorically sure as all that.
    I can think of at least one way.

    Construct a minimal web server on the local machine and access it via ajax.

    Or find some mechanism where JavaScript or the browser interacts with
    the host, and subvert it...

    For this you need Node.js:

    <https://nodejs.org/api/http.html#http_http_createserver_options_requestlistener>

    Or setup Apache2 or Nginx.

    I'm not sure if I'd call this a "workaround". To me this seems to be a completely different approach - don't access locally but using a webserver.

    Well yes, semantics is one thing, bits in silicon is another.
