Write a detailed guide on building a Firefox browser extension for Linux that monitors how much time I spend on different websites
Output
Here's a detailed guide on creating a Firefox browser extension to track website usage time on Linux:
| # Building a Website Time Tracker Extension for Firefox
## Prerequisites
- Basic knowledge of JavaScript, HTML, and CSS
- A text editor (VS Code, Sublime Text, etc.)
- Firefox browser installed
- Node.js and npm (for development tools)
## Project Structure
|
website-timer/
├── manifest.json
├── background.js
├── popup/
│ ├── popup.html
│ ├── popup.css
│ └── popup.js
└── icons/
├── icon-48.png
└── icon-96.png
| ## Step 1: Create the manifest.json
Create a `manifest.json` file that defines the extension's properties:
|
json
{
"manifest_version": 2,
"name": "Website Time Tracker",
"version": "1.0",
"description": "Track time spent on different websites",
"permissions": [
"tabs",
"storage",
"activeTab",
"webNavigation"
],
"background": {
"scripts": ["background.js"],
"persistent": false
},
"browser_action": {
"default_popup": "popup/popup.html",
"default_icon": {
"48": "icons/icon-48.png",
"96": "icons/icon-96.png"
}
},
"icons": {
"48": "icons/icon-48.png",
"96": "icons/icon-96.png"
}
}
| ## Step 2: Create the Background Script
Create `background.js` to handle time tracking:
|
javascript
// Store active tab information
let activeTab = {
id: null,
url: null,
startTime: null
};
// Store website time data
let websiteTime = {};
// Load saved data
browser.storage.local.get('websiteTime').then((result) => {
if (result.websiteTime) {
websiteTime = result.websiteTime;
}
});
// Track active tab changes
browser.tabs.onActivated.addListener(async (activeInfo) => {
const tab = await browser.tabs.get(activeInfo.tabId);
updateActiveTab(tab);
});
// Track URL changes
browser.tabs.onUpdated.addListener((tabId, changeInfo, tab) => {
if (changeInfo.url) {
updateActiveTab(tab);
}
});
// Update active tab and record time
function updateActiveTab(tab) {
if (activeTab.url) {
// Record time spent on previous tab
const timeSpent = Date.now() - activeTab.startTime;
const domain = new URL(activeTab.url).hostname;
if (!websiteTime[domain]) {
websiteTime[domain] = 0;
}
websiteTime[domain] += timeSpent;
// Save to storage
browser.storage.local.set({ websiteTime });
}
// Update active tab information
activeTab = {
id: tab.id,
url: tab.url,
startTime: Date.now()
};
}
| ## Step 3: Create the Popup Interface
### popup.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="popup.css">

justify-content: space-between;
margin: 5px 0;
padding: 5px;
border-bottom: 1px solid #eee;
}
.website-name {
font-weight: bold;
}
#reset-button {
margin-top: 10px;
padding: 5px 10px;
background-color: #ff0000;
color: white;
border: none;
border-radius: 4px;
cursor: pointer;
}
javascript
// Format time function
function formatTime(ms) {
const seconds = Math.floor(ms / 1000);
const minutes = Math.floor(seconds / 60);
const hours = Math.floor(minutes / 60);
if (hours > 0) {
return `${hours}h ${minutes % 60}m`;
} else if (minutes > 0) {
return `${minutes}m ${seconds % 60}s`;
} else {
return `${seconds}s`;
}
}
// Display statistics
async function displayStats() {
const statsContainer = document.getElementById('stats-container');
const result = await browser.storage.local.get('websiteTime');
const websiteTime = result.websiteTime || {};
// Sort websites by time spent
const sortedWebsites = Object.entries(websiteTime)
.sort(([, a], [, b]) => b - a);
statsContainer.innerHTML = '';
for (const [domain, time] of sortedWebsites) {
const div = document.createElement('div');
div.className = 'website-stat';
div.innerHTML = `
<span class="website-name">${domain}</span>
<span class="time-spent">${formatTime(time)}</span>
`;
statsContainer.appendChild(div);
}
}
// Reset statistics
document.getElementById('reset-button').addEventListener('click', async () => {
await browser.storage.local.set({ websiteTime: {} });
displayStats();
});
// Update statistics every second
displayStats();
setInterval(displayStats, 1000);

1. Open Firefox and go to `about:debugging`
2. Click "This Firefox" on the left sidebar
3. Click "Load Temporary Add-on"
4. Navigate to your extension directory and select `manifest.json`
## Step 5: Publishing the Extension (Optional)
To publish your extension to Firefox Add-ons:
1. Create an account at https://addons.mozilla.org
2. Package your extension (zip all files)
3. Submit for review
## Additional Features to Consider
1. Data visualization using charts
2. Daily/weekly/monthly statistics
3. Website categories
4. Time limits and alerts
5. Data export functionality
6. Blacklist/whitelist for tracking
## Debugging Tips
1. Use `console.log()` in background.js
2. Check the browser console for errors
3. Use Firefox's built-in debugging tools
4. Test on different websites
## Notes
- The extension uses local storage, so data persists between browser sessions
- Time tracking may not be 100% accurate when the browser is inactive
- Consider adding data backup functionality
- Test thoroughly with different website URLs and browser states
This extension provides basic time-tracking functionality and can be extended with additional features based on your needs.

6. Create icons for your extension:
Create two PNG files for the extension icon:
- icons/icon-48.png (48x48 pixels)
- icons/icon-96.png (96x96 pixels)
7. Testing the extension:
| # In Firefox, navigate to
about:debugging
# Click "This Firefox"
# Click "Load Temporary Add-on"
# Navigate to your extension directory and select manifest.json
|
8. To package the extension for distribution:
| # Install web-ext tool
npm install --global web-ext
# Build the extension
web-ext build
# The packaged extension will be in the web-ext-artifacts directory
|
Features of this extension:
- Tracks time spent on each website by domain
- Continues tracking when switching between tabs
- Pauses tracking when the browser window loses focus
- Provides a popup interface showing time spent on each site
- Allows clearing of statistics

7. Add icons to the icons folder:
You'll need to create or download two icon files:
- icon-48.png (48x48 pixels)
- icon-96.png (96x96 pixels)
8. Testing the extension:
a. Open Firefox and go to `about:debugging`
b. Click "This Firefox" in the left sidebar
c. Click "Load Temporary Add-on"
d. Navigate to your extension directory and select the manifest.json file
9. To package the extension for distribution:
| zip -r my-time-tracker.zip manifest.json background.js popup/ icons/
|
Features of this extension:
- Tracks time spent on different domains
- Continues tracking even when switching tabs
- Displays statistics in a popup window
- Shows time in hours, minutes, and seconds
- Allows resetting statistics
- Persists data between browser sessions
- Automatically groups subdomains under their main domain
Additional improvements you could make:
- Add daily/weekly/monthly statistics
- Export data to CSV
- Set time limits for specific websites
- Add charts and visualizations
- Implement site categories
- Add idle time detection
- Create detailed reports
Remember that this is a basic implementation, and you might want to add error handling, data validation, and additional features based on your specific needs.

4. To install and test the extension:
1. Open Firefox and go to `about:debugging`
2. Click "This Firefox" in the left sidebar
3. Click "Load Temporary Add-on"
4. Navigate to your extension directory and select `manifest.json`
The extension will now:
- Track time spent on each website
- Display statistics in a popup when clicking the extension icon
- Save data between browser sessions
- Allow resetting statistics
- Handle browser focus changes
- Format time in a readable way
- Sort websites by time spent
Additional improvements you could make:
1. Add daily/weekly/monthly statistics
2. Create data visualization (charts/graphs)
3. Add export functionality for the data
4. Implement site categories or tags
5. Add idle detection to pause tracking
6. Create website blacklist/whitelist
7. Add custom time goals and alerts
To package the extension for distribution:
1. Create a `.zip` file of your extension directory
2. Create an account on [Mozilla Add-ons](https://addons.mozilla.org/developers/)
3. Submit your extension for review
4. Once approved, users can install it from the Firefox Add-ons store
Remember to keep the extension's permissions to a minimum and handle user data responsibly.
