Mozilla Add-on SDK - OS.File.read (The system cannot find the file specified.)

I created an add-on following Mozilla's tutorials. cfx test and cfx run worked perfectly. I put the folder on my desktop and installed the add-on into Firefox using cfx xpi and Ctrl+o (the xpi file).

Now the add-on gives this error in the console log:

Win error 2 during operation open on file purls.txt (The system cannot find the file specified.)

Here is the relevant code in main.js:

const {TextEncoder, TextDecoder, OS} = Cu.import("resource://gre/modules/osfile.jsm", {});
let decoder = new TextDecoder();
let promise = OS.File.read("purls.txt").then(
    function onSuccess(array) {
        // Do stuff
    },
    function onReject(reason) {
        console.error("Couldn't read from purls.txt:\n"+reason);
    }
);

Please help me figure out what is going on. When I use cfx run the add-on finds the purls.txt file and opens it/reads from it without problem.

You didn't give it a path to purls.txt, so it was probably looking for purls.txt on your drive. Is it on the desktop? Then create a path to the desktop. See pathToPurls;

const {TextEncoder, TextDecoder, OS} = Cu.import("resource://gre/modules/osfile.jsm", {});
let decoder = new TextDecoder();
let pathToPurls = OS.Path.join(OS.Constants.Path.desktopDir, "purls.txt");
console.log('pathToPurls:', pathToPurls);
let promise = OS.File.read(pathToPurls).then(
    function onSuccess(array) {
        // Do stuff
    },
    function onReject(reason) {
        console.error("Couldn't read from purls.txt:\n"+reason);
    }
);
