Overview

This extension is an email Tracker Blocker, hence the name: Trocker!

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! If you have any issues with Trocker, email us at trockerapp@gmail.com or report the issue on GitHub (https://github.com/trockerapp/trocker/issues). Thanks for reporting issues. Given that Trocker needs to react to any breaking changes in webmails, we may not know about new issues unless you report them. Also, please consider giving us a chance to fix the issues before leaving a bad rating/review. And follow us on twitter: https://twitter.com/trockerapp More information: You can trust Trocker! Trocker runs locally on your machine and does not send or receive any information from the Internet. It needs permission to all tabs in order to be able to detect and prevent any tracking images or tracked links from being loaded from any of the tabs. But it makes absolutely no outbound Internet access and we neither gather nor use any data about you or your browsing behavior. Trocker is also open source with the source code available at https://github.com/trockerapp/trocker and we encourage everyone to check it out from there or from Chrome Dev tools to confirm that there are no suspicious activities being done. 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. Technical details: Some email trackers track emails by injecting an invisible small image in the mail that is hosted in a specific address in their server. They know when the email is opened by looking at the download requests of the injected images on their servers. Trocker (as a lovely Tracker Blocker) stops this by simply blocking those image links from being loaded. It finds those injected images by looking at the url and matching the url pattern with the tracking servers that host injected images. If you yourself are a user of these tracking services (you track emails you send others), your service wouldn't be affected and will work fine. Trocker would only defend you from OTHERS tracking you. Moreover, some links are click tracked meaning that if you click on them, your clicks are logged and tracked. Trocker tries to bypass those links and redirect you directly to the original target without you being tracked. If not possible, Trocker will inform you that the link you've clicked on is tracked. No one will be able to know when and if you open their emails, or click on their links if you enable Trocker. In Gmail, Inbox and Outlook.com, Trocker has a heuristic tracker detection that will detect and block almost any tracker, even if it is unknown. This works based on the fact that very tiny images are almost always trackers. After all, if they want you to see the image, they will make it bigger than 1x1 pixel! Change log: 3.0.2: - Fixes Google chat images not loading. - Fixes Gmail tool bar third party icons not loading. 3.0.1: - Fixed bug with service worker not starting at all. 3.0.0: - This release makes Trocker compatible with the newly mandated Manifest V3, which required significant rewriting of all blocking/redirecting features since the API we used before (webRequestBlocking) to block tracking images/links before they loaded is no longer available for extensions to use. - In the new Manifest V3, with the declarativeNetRequest API, we are only allowed to block images/urls that match pre-specified domains. - This means that we can only block listed trackers and all trackers in webmails that use proxies to load all images. Only Gmail and Yahoo mail consistently load images via proxy urls, so we can block all proxied images from these webmails unless they are proved safe and whitelisted. - For Outlook, unfortunately images are not loaded with a proxy (at least not consistently as of June 2024), so in Outlook, Trocker will only be able to (i) expose all tracked emails, (ii) block tracked emails that use pre-known tracking services. Blocking unknown trackers in Outlook is the only functionality from the previous versions of Trocker that we could not implement in the new version. 🎉 - Background page has been replaced with a service-worker page as required by Manifest V3. - Tracked emails are now marked with a red envelope if Trocker was only able to expose the trackers but was not able to block them (e.g. in Outlook). - A blue envelope means that Trocker both exposed and blocked the trackers in the email. - Show live blocked/exposed statistics in the settings page. - Various other visual updates in the settings and change log pages. 2.7.0: - Improves handling of drafts, print previous, quotes, and general stability in YMail, Outlook and Gmail. - Adds visual debugging tools for webmails. - Adds info on options for supporting Trocker. 2.6.27: - Improves handling of drafts and general stability in YMail. 2.6.26: - Improves handling of changes in email content. - Adds support for new Gmail proxy url. - Fixes Outlook attachment preview blocking issue that only affected Firefox. 2.6.24: - Adapts to changes in Gmail. 2.6.23: - Adds support for new Outlook design updates. 2.6.21: - Adds support for new Outlook design updates. 2.6.20: - Fixes Outlook sidebar icon issue in Firefox. 2.6.19: - Fixes Outlook sidebar icon issue in Firefox. 2.6.16: - Adapts to new under the hood changes in Outlook. - Adds more known trackers to block list. 2.6.15: - Fixes Yahoo/Outlook bug in the new heuristic. - Adds graceful handling of lost connection to extension context after updates. 2.6.14: - Adds heuristic detection of tracking images based on patterns in the url. 2.6.12: - Fixes handling of attachments in Outlook. - Improves logs for easier debugging. 2.6.11: - Improves handling of webmails that load images gradually (e.g. Outlook). - Adds Trocker version to options and logs. 2.6.10: - Adds support for classic Yahoo mail. 2.6.9: - Fixes interference with Gmail's signature switch. 2.6.8: - Adds advanced option to customize known open/click tracker lists. - Adds more known trackers to universal block list. 2.6.7: - Fixes new issue with Gmail sidebar that blocked some extension icons. 2.6.5: - Fixes new issue that blocked some Outlook UI images. - Adds blocking for additional known trackers. - Improves heuristic detection of trackers. 2.6.4: - Fixes new Yahoo mail proxy issue that blocked all images. - Improves handling of data-images. 2.6.3: - Improves detection of hidden tracking images. - Adds the option to change tracked link bypass timeout. 2.6.2: - Adds support for the outlook.office.com url for Outlook. 2.6.1: - Adds support for the updated outlook.com and office365. 2.6.0: - Improves mail.yahoo.com support. - Blocks additional trackers. - Improves the options page. 2.5.2: - Makes non-essential permissions optional (for more info see the Trocker options). - Improves outlook.com support. - Improves the options page. 2.4.3: - Adds support for outlook.office365.com. 2.4.2: - Adds support for the new outlook.com. 2.4.1: - Adds support for Firefox. 2.3.7: - Improves tests.
