PixelBlock: Block Email Tracking in Gmail

PixelBlock is a Chrome extension that allows Gmail users to block email tracking attempts. This tool safeguards your privacy by preventing email senders from knowing when you open and read their emails. PixelBlock is effective, user-friendly, and displays a 'red eye' symbol as an indicator when it successfully blocks a tracking attempt.

Used this for years, really loved it, I hope it is updated soon so it will work again with Chrome MV3.

As of 3rd March, the extension doesn't seem to be compatible with Chrome anymore and has been switched off in my browser.
