Email Tracker for Firefox 作者： Kartikeyan Rai

Email Tracker for Firefox helps you know when your emails are opened. It adds a 1x1 invisible tracking pixel to your outgoing emails (e.g., via Gmail). When the recipient opens the email, the pixel is loaded, and you'll get notified. Features include:

• Automatic pixel injection in compose window
• Real-time tracking of open events
• Simple dashboard to view tracking logs
• 100% private — data only stored on your local backend or server

Great for outreach, follow-ups, and productivity! Compatible with Gmail and other webmail clients.
