Features & Capabilities

Trocker is a powerful Chrome extension designed to protect your email privacy by blocking email trackers. Many emails contain invisible tracking images or tracked links that notify senders when you open or interact with their messages. Trocker stops these tracking attempts by locally blocking requests for tracking images and bypassing tracked links without sending any data to the internet.

Compatible with popular webmail services like Gmail, Yahoo, and Outlook, Trocker even offers advanced heuristic detection in Gmail, Inbox, and Outlook to block nearly all trackers, including unknown ones. It runs efficiently, activating only when trackers are detected, and is fully open source to ensure transparency and trust. With Trocker enabled, no sender can know when you open their emails or click their links, giving you complete control over your email privacy.

Is Trocker Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Trocker requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Trocker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
