Doesn't work.

Specifications

Script

// ==UserScript==
// @name         New Userscript
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://github.com
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    alert("Da");
})();

I tried on github.com and dropbox.com and it doesn't work at all. On wikipedia.org, for example, the same simple alert works.

[erosman]

@match https://github.com

Invalid match patterns: no path
ref: Match Patterns
About Permissions for Scripts and Style Sheets

Try

// only top page
 @match        https://github.com/

// all github pages
 @match        https://github.com/*

That's how Tampermonkey generated it when I opened github.com and then used the "Create a new script...". I tried with https://github.com/ to no avail. Same with https://github.com/*.

The thing is that the add-on icon gets correctly badged:

But not alert shows up. Did it work for you?

[erosman]

Did it work for you?

TBH, I was looking for something and I came across your post and replied with what I noticed.
I am afraid I am not a TM user to test it out.
Sorry

@revolter Are there console messages regarding a Content Security Policy violation?
If so, then this is a duplicate of #296 (comment)

[revolter]

I don't think so, as it shows

regardless of whether the script is enabled or not.

Could you please try yourself to create a script that does anything on github.com and let me know if it works?
