Not working. I have this extension installed, and I've just received an email from a colleague in which it is clearly said "Remitente notificado con Mailtrack" ("sender notified with Mailtrack")

01/20/2024: WELL, Omar??? 12/15: NOPE. Pixelblock does NOT successfully BLOCK the Mailtrack for Gmail tracker! Protonmail DOES. I would rather rely on your extension and unsure why you would say it was "fixed". Maybe you assumed so but didn't test it. Get it working and I will gladly go to 4/5 stars. Thanks for your efforts. 12/7: The blocked red eye icon finally reappeared for the last month or so, ONLY to disappear today with the Chrome update. Please fix and thanks! 12/13: THANKS OMAR! *BUT* Pixelblock does NOT block MAILTRACK for GMAIL (mailtrack.io)? What's up with that? Should I know of this limitation already? The "red eye" leads me (and others) to believe that not only was a pixel or pic blocked, but that the *TRACKING* pixel was blocked. Can you recommend another extension that can block Mailtrack tracking?

Images are back when authorized, but the 'eye' icon is still not displayed. Please fix this. Thank you very much. (In the meantime, I grant this extension five stars, as it is a useful one when working properly.) March 11: I'm downgrading by two stars since the extension has been blocking all images again for several days ― having lost time looking for the problem elsewhere before realizing that it was simply here. March 12 : Thank you for getting it 'up and running' again!

Blocks all images in Gmail now. Abandoned by developer. Was great while it lasted.

Echoing others. Used to be great (5 stars). Worked effectively for years. It now blocks ALL IMAGES in Gmail. I had to disable it. I hope they fix it.

Used to be a good extension. Now it breaks all images in Gmail. Nice fail, been using for years and now it's junk.

Still blocks images so still prevents the sender from knowing when you open their emails. However the option to "Allow images below" doesn't seem to work anymore. It looks like it was last updated in April 2019. I have used this extension for years and loved it but I would like to be able to Allow some emails to display their images. I'm leaving it installed and hope the creator comes back and updates the code. Thanks for the years of service @omar.w.qureshi

I've used this extension for a VERY long time. As others have noted, something broke due to either Google/Extension around Nov 1, 2023. No word from the dev, so moving over to this Email Privacy Protector https://chrome.google.com/webstore/detail/email-privacy-protector-i/ocodabmcnjfjeioonacpommjjlmhbccg/related
