In order to access extension's localStorage you need to send a request to your background page:

In script.js:

chrome.extension.sendRequest("getStorageData", function(response) {
    console.log("response:", response);
}

In background.html:

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
    if(request === "getStorageData") {
        sendResponse(localStorage["data"]);
    }
});
