javascript - "Cannot read property of undefined" when using chrome.tabs or other chrome API in content script

Question

chrome.tabs returns undefined despite the fact I set tabs in the permissions block.

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

But in myScript.js the following returns undefined.

chrome.tabs   

Answer 1

As content script has its own limitations,

chrome.tabs is only available in background scripts and popup scripts.

If you wanna to use chrome.tabs then pass message from content_script to background script and play with chrome.tabs.
