#41000 — Cross-Origin Request Blocked

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.

Accessing local files is restricted for security reasons.

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.
