Trocker for Firefox

Trocker for Firefox is a quick and simplistic browser enhancer that goes a long way in terms of privacy protection and increase.

Although the vast majority of users tend to ignore the need for more online security and not pay attention to elements that are intrusive in their online activity, in recent years, more and more initiatives focus on providing simple and zero-configuration methods and tools for exposing and preventing online tracking of any kind.

As such, Trocker for Firefox is an open-source and free extension that is available for both Firefox and Chrome. The add-on is mild on your system's resources, does not require any initial configuration, and exposes and blocks email trackers, small scripts and tools that have dedicated features for notifying the sender about whether or not you have opened the email they sent or if you have clicked/interacted with the content they provided in the mail.

As previously mentioned, you don't need to do anything when adding this add-on to your browser, and there is no need for you to sign up anywhere or to go through an initial setup.

However, if you want to perform a more extensive exposing activity for all those trackers, you can simply click the icon that gets added to your toolbar and check Trocker's settings page. There, you will find detailed explanations for other functions (different from the defaults) you can enable.

For example, you can enable the add-on for all websites and expand its tracking activity, or you can enable the 'Expose Trackers' feature that has a dual function: it makes visible tracked in-mail images as block-listed trackers or auto-detected trackers, and it changes the mouse pointer into an icon that signal the links that are tracked.

Last but not least, you can enable or disable the tracker counter. This is a function that displays the number of trackers that you have in an email.
