Trocker Browser Extension
You can add it to
Block trackers from seeing what you do with your emails
- Tracking your emails to know if the receiver has opened them or not is awesome, so is being immune to it! Trocker gives you the latter! It blocks attempts by email trackers and won't let them track what you do with the emails you receive.
- You will be amazed to see how many of the emails you receive have trackers in them!
- Trocker is open source so you can trust it. Source code available on GitHub.
- Trocker keeps you safe in all webmails, including Gmail™, Yahoo! and Outlook.com. It has additional capabilities in Gmail, Inbox and Outlook.com. In these 3 webmails, it has a heuristic tracker detection that detects and blocks almost any email tracking attempt, even from not well-known trackers!
- Trocker is very efficient as it only gets activated when a tracker is detected.

Frequently asked questions
- I had an email which I know was tracked, but Trocker did't block it. Why?
First, please enable Trocker in incognito/private mode and repeat your test there. In incognito/private mode only extensions you specifically approve can run so if the issue persists it confirms that the issue is not due to interference from other extensions.
We have indeed observed that certain other extensions (which were ironically email tracking extensions) spy on their own customers and enable trackers behind the scenes. You can read more here.
Second, some tracking images cannot be easily blocked because they don't have any size information that would enable Trocker to guess that they are trackers before they are loaded. Maybe you had one of those. In this case, we can add the url of the tracker to our black list if it is not already there. Please consider forwarding the email in question to us at email@example.com (after removing any personal information) so that we can do that.
- Why does Trocker require permission to "Access your data for all websites"?
In order to be able to block a tracking image, the browser should tell Trocker before loading that image. Technically, for this to happen for all potential tracking images from any url, Trocker requries a permission called <all_urls>, otherwise only a specific set of tracking urls will be blockable. This is a powerful permission in general so browsers rightfully describe it as "Access your data for all websites". Without this permission, blocking of email trackers will be limited to a few webmails or to a specific predetermined list of trackers. For more info about the technical details, see this issue on GitHub.
- Trocker has recently stopped working correctly in Gmail/Yahoo/Outlook! Why?
Every once in a while, these webmails undergo design changes that Trocker needs to adapt to in order to function correctly. If you notice that something has stopped working correctly, such design changes may be the reason. Please report the issue by emailing us at firstname.lastname@example.org or opening an issue on GitHub.
