Features & Capabilities

Ever wonder who knows the exact moment you open an email? Sales and marketing tools like Mailtrack, HubSpot, Yesware and Streak embed invisible "spy pixels" to track you. WhoSpies reveals them — by name.

WHY WHOSPIES IS DIFFERENT Other extensions just say "a tracker was found." WhoSpies tells you "HubSpot tracked you 7 times, always from contact@company.com." That difference changes what you can do with the information.

MAIN FEATURES • Blocks the tracker: neutralizes spy pixels in the message — most effective on Outlook; on Gmail, image proxying may limit it. Three protection levels (off / balanced / strict). • Names the service: see the real tracker (Mailtrack, Yesware, HubSpot, Streak, SalesLoft, ActiveCampaign and more) right inside each email. • History per sender: how many times each person or company tried to track you, and with which tool. • "Who spies on you most" view: a ranking you can sort by sender or by service. • Works on Gmail and Outlook web from a single extension. • Built-in signature catalog: 29 known email trackers plus generic pixels, expanded with each new version.

YOUR PRIVACY, GUARANTEED All matching and history happen on your device. No email, sender address or personal data ever leaves your browser. You can erase the full history in one click.

PERMISSIONS Only local storage access. No unnecessary network permissions, no access to your passwords or browsing history.

SUPPORT WhoSpies is free. If it's useful to you, you can support development via PayPal or Ko-fi (links inside the extension).

Is whospies-email-tracker-blocker 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.

whospies-email-tracker-blocker requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.
