The following code doesn't work for some reason:

Background.js

alert("1");
chrome.cookies.set({ url: "", name: "SuperDuperTest" });
alert("2");

manifest.json

"permissions": [ "notifications", "", "cookies", "http://* /* ", "https://* / * " ],

Only alert("1"); ever fires. Alert 2 never does, why isn't my chrome cookies firing at all?

• What does the javascript console say? – John Dvorak Commented Jan 21, 2013 at 22:05
• 1 I can't see any chrome.cookies in my console. Is that a specialty just for extensions? – John Dvorak Commented Jan 21, 2013 at 22:10
• Yeah mine is blank too, thats why I'm using alerts. – Stan Lindsey Commented Jan 21, 2013 at 22:30

Where are looking to check whether your cookie is set or not? Please use console.log() instead of alert()

Sample Code

manifest.json

Registered background page and given permissions for Cookies API.

{
    "name": "Cookie API Demo",
    "version": "1",
    "description": "http://stackoverflow./questions/14448039/chrome-cookies-set-doesnt-even-run",
    "permissions": [
        "cookies",
        "<all_urls>"
    ],
    "background": {
        "scripts": [
            "background.js"
        ]
    },
    "manifest_version": 2
}

background.js

Trivial code to set cookie for cookies.html page

chrome.cookies.set({
    "name": "Sample1",
    "url": "http://developer.chrome./extensions/cookies.html",
    "value": "Dummy Data"
}, function (cookie) {
    console.log(JSON.stringify(cookie));
    console.log(chrome.extension.lastError);
    console.log(chrome.runtime.lastError);
});

Output

Go to https://developer.chrome./extensions/cookies.html and open developer tools as shown here, you can see cookie is being set!.

Further Debugging

If this sample code does not work, what are values of chrome.extension.lastError and chrome.runtime.lastError?

Make sure you declared the cookies permission.

To use the cookies API, you must declare the "cookies" permission in your manifest, along with host permissions for any hosts whose cookies you want to access. For example:

{
  "name": "My extension",
  ...
  "permissions": [
    "cookies",
    "*://*.google."
  ],
  ...
}

source: developer.chrome.
