My session and CSRF token data are saved in a script referenced by my popup.html file. But my request is being sent from a content script. How can my content script get data from popup.js, referenced in popup.html

to achieve communication between the content script and `popup.js`, you can use the background script as a mediator. here's a step-by-step process to illustrate how you can get data from `popup.js` to your content script. 

1. create a background script. if you don't already have one, you can create a new javascript file, e.g., `background.js`. don't forget to add it to your `manifest.json` file like so:

```json
"background": {
  "scripts": ["background.js"],
  "persistent": false
},
```

2. in `popup.js`, send a message to the background script when you want to save session and csrf token data:

```javascript
chrome.runtime.sendmessage({
  action: "savesessionandtoken",
  session: "<session-data>",
  csrftoken: "<csrf-token>"
});
```

3. in the `background.js`, listen for messages from `popup.js`, and save the session and csrf token data:

```javascript
let sessiondata = null;
let csrftokendata = null;

chrome.runtime.onmessage.addlistener((request, sender, sendresponse) => {
  if (request.action === "savesessionandtoken") {
    sessiondata = request.session;
    csrftokendata = request.csrftoken;
  }
});
```

4. in your content script, whenever you need the session and csrf token data, send a message to the background script:

```javascript
chrome.runtime.sendmessage({ action: "getsessionandtoken" }, (response) => {
  console.log("session: ", response.session);
  console.log("csrf token: ", response.csrftoken);
});
```

5. lastly, in the `background.js` file, listen for this new message from the content script, and send back the session and csrf token data:

```javascript
chrome.runtime.onmessage.addlistener((request, sender, sendresponse) => {
  // existing code for saving the session and csrf token
  if (request.action === "savesessionandtoken") {
    sessiondata = request.session;
    csrftokendata = request.csrftoken;
  }

  // new code for sending the session and csrf token to the content script
  if (request.action === "getsessionandtoken") {
    sendresponse({ session: sessiondata, csrftoken: csrftokendata });
  }
});
```

now, your content script will be able to access the session and csrf token saved in `popup.js` by communicating with the background script.

    sessionData = request.session;
    csrfTokenData = request.csrfToken;
  }
});
```

4. In your content script, whenever you need the session and CSRF token data, send a message to the background script:

```javascript
chrome.runtime.sendMessage({ action: "getSessionAndToken" }, (response) => {
  console.log("Session: ", response.session);
  console.log("CSRF Token: ", response.csrfToken);
});
```

    csrfTokenData = request.csrfToken;
  }

  // New code for sending the session and CSRF token to the content script
  if (request.action === "getSessionAndToken") {
    sendResponse({ session: sessionData, csrfToken: csrfTokenData });
  }
});
```

Now, your content script will be able to access the session and CSRF token saved in `popup.js` by communicating with the background script.
