    Version 3.3.1

    Released Jan 26, 2026 - 121.58 KB
    Works with firefox 109.0 and later
    3.1.1:
    - Added support for Yahoo's new image proxy format and DOM design.
    - Fixed a bug that caused image flickering in compose windows in Yahoo mail on Firefox.
    - Adds more known trackers to universal block list.

    3.3.0:
    - Improved permission check: Checks for required permissions on startup and guides you to the settings page if they are missing. Important for Firefox since Firefox does not automatically grant permissions or warn the user about missing permissions.

    3.2.0:
    - Fixes the new bug in Firefox where tracked link forwarding would cause an infinite loop.

    3.1.2:
    - Fixes infinite redirect loop on tracked links in Firefox.

    3.1.0:
    - Adds Manifest V3 support for Firefox bringing it to parity with Chrome.
    - Fixes console errors and improved stability.

    3.0.4:
    - Improves tracker detection in background images.

    3.0.3:
    - Fixes bug in the relevant Trocker setting being able to control the count down time in the tracked link bypasser.

    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.
