I’m in dire need of a script that gathers all of my Firefox tabs in a list

ChatGPT

Here’s a simple Python script that retrieves all open Firefox tabs and lists them. It uses the pygetwindow and pyperclip libraries along with JavaScript execution through Firefox’s Developer Tools.

ChatGPT

This script provides a way to extract all open Firefox tabs by leveraging the browser’s Developer Tools and clipboard functionality. Follow the printed instructions to execute the JavaScript snippet, which will copy all open tab URLs to your clipboard. Then, the script will retrieve and display them.

I want to organize them in a markdown table, each tab should have a page title and a url ,as well as the date last accesed (if available)

ChatGPT

I’ve modified the script to generate a Markdown table containing each tab’s title, URL, and last accessed date (if available). The table will be printed as output, making it easy to copy and use elsewhere. Let me know if you need further refinements! 🚀

save the markdown file

ChatGPT

I’ve updated the script to save the markdown table to a file named firefox_tabs.md. Let me know if you need any modifications! 🚀

(async () => {

let tabs = await browser.tabs.query({});

let tabData = tabs.map(tab => ${tab.title} | ${tab.url} | ${tab.lastAccessed ? new Date(tab.lastAccessed).toLocaleString() : 'N/A'}).join(‘\n’);

console.log(tabData);

copy(tabData);

})();

Promise { : “rejected”, : ReferenceError }

ChatGPT

It looks like the JavaScript snippet is failing due to a ReferenceError. This could be happening for a few reasons:

1. Missing Browser Extension API (browser.tabs.query)

   • The browser.tabs API is only available in Firefox extensions, not directly in the developer console.
   • If you want to run this in the console, use chrome.tabs.query instead (but that works only in Chrome, not Firefox).

2. Clipboard Permission Issue (copy function not found)

   • The copy function is available in the Developer Console in Chrome but not in Firefox.
   • In Firefox, you may need to manually copy from console.log(tabData).

Fix for Running in Firefox Console:

Use the navigator.clipboard.writeText() API instead of copy(), and ensure the script runs in the correct context.

(async () => {
  let tabs = await browser.tabs.query({});
  let tabData = tabs.map(tab => `${tab.title} | ${tab.url} | ${tab.lastAccessed ? new Date(tab.lastAccessed).toLocaleString() : 'N/A'}`).join('\n');

  console.log(tabData);

  try {
    await navigator.clipboard.writeText(tabData);
    console.log("Copied to clipboard!");
  } catch (err) {
    console.error("Failed to copy:", err);
  }
})();

Steps to Run in Firefox:

1. Open Firefox Developer Tools (F12 or Ctrl + Shift + I).
2. Go to the Console tab.
3. Paste the updated script above and press Enter.
4. The output will be logged in the console and copied to the clipboard.

The error occurs because browser.tabs.query is part of the WebExtensions API, which is only available inside Firefox extensions, not directly in the Developer Tools Console.

Solution: Use window.open to Get Tabs Instead

Since the WebExtensions API doesn’t work in the console, we need a workaround. Here’s an alternative approach using document visibility and window.open:

1. Updated JavaScript for Console Execution

(async () => {
    let tabs = [];

    // Get all open windows and their tabs
    for (let win of await chrome.windows.getAll({populate: true})) {
        for (let tab of win.tabs) {
            tabs.push(`${tab.title} | ${tab.url} | N/A`);
        }
    }

    let tabData = tabs.join('\n');
    console.log(tabData);

    // Copy to clipboard
    try {
        await navigator.clipboard.writeText(tabData);
        console.log("Copied to clipboard!");
    } catch (err) {
        console.error("Failed to copy:", err);
    }
})();

Steps to Run in Firefox

1. Open Firefox Developer Tools (F12 or Ctrl + Shift + I).
2. Navigate to Settings and enable Enable browser chrome and add-on debugging.
3. Open the Browser Console (Ctrl + Shift + J or Cmd + Shift + J on macOS).
4. Paste the above JavaScript code and press Enter.
5. The output will be printed in the console and copied to your clipboard.

This script retrieves all tabs from all open windows and stores them in a clipboard-friendly format.

Updating Your Python Script

Now that we have fixed the JS snippet, your Python script can remain the same. Just replace the old tabs_js snippet in your script with this new one.

Would you like me to update the Python script for you with this fix? 🚀
