尽管我在权限块中设置了标签,但chrome.tabs仍返回undefined.

"permissions": [
    "tabs",
    "http://*/*",
    "https://*/*"
],
"content_scripts": [
    {
        "matches": [
            "http://*/*",
            "https://*/*"
        ],
        "js": [
            "js/myScript.js"
        ],
        "all_frames": true
    }
],

但是在myScript.js中,以下内容返回undefined.
