Do you know that most of the emails you have received have a timid, secret tracking pixel designed to snup to you? Whether spam, marketing, or otherwise, these tracking can send the information back to send the pixel – unless you install one of these trackers pixel blocking extensions.

Pixelblock is one of the easiest tracker-blocking extensions to use so far. This does not require any setup or complex configuration. Head on Pixelblock chrome web store pageAdd extension to Chrome, and this is the case. Every time you detect and block the pixel in your email, you will see a red eye icon every time.
However, if you use anything other than Gmail and a non-chromium browser (eg these Firefox-based browser), then you are out of luck. The pixelblock is as convenient as it works only on Gmail and is available only to chromium-based browsers such as chrome, age, brave, and more. There is a possibility that you already have a Gmail account and are currently using a chromium-capable browser. But if you are not, then read.
Another great choice for Gmail tracker blocker is ugly email. The extension is an open source and already has more than 50,000 users Chrome Web StoreAnd if you are not a chrome fan or do not use chromium-based browser, there is also there Firefox version Available.
It works very equally for pixelblock, in this you install it once and do not need to do anything else. Once established, the extension automatically scans your inbox and looks for an email with tracking pixel. Any email with trackers in them is then labeled with an eyeball icon, and trackers are immediately blocked. If you hover the icon, you can also see which extension the tracker is blocking.
All the data of the extension are stored in the IndexDB storage of your browser, which means it works locally and no data ever leaves your browser. The extension does not track you or also does not access your email. If you suspect, you can always go Jethb repository To check the source code.
If you are looking for a size-fit-all solution to block email trackers, then as close as you are as close. The extension is open-source, which is available for both chrome and chromium-based browser Chrome Web StoreAnd it is also Firefox version,
Unlike pixelblock or ugly email, the trocker claims to work on all webmails. This means that as long as you use your email in a browser with installed extensions, you will be protected from trackers. In Gmail, Yahoo and Outlook, the extension also includes hyuristic tracker detection, which “detects and blocks almost any email tracking effort, not even from the famous trackers.”
The trocker also goes to the extra mile and shows you exactly that the hidden tracking is located in the image or pixel email. You will also see a “T” icon on the tracked email, and any traveled link will be highlighted with a special icon when you are hovering over them.
There is also a rather basic settings menu where you can choose to block or unlock trackers, decide whether to expose them in your email, and see the count of the current tab tracker. The extension also moves locally, which means that no data ever leaves your browser. You can check the safety of chrome extension before installing, but Jethb repository If you want to verify its claims, want to present a problem, or contribute to development.
You can know the Ublock origin as an advertising inhibitor available for both Chromium And Firefox Browser. However, the extension tracker also comes with a set of blockers that can block the email tracked in various webmail interfaces.
He said, for Ublock origin, you need to set it properly to avail the maximum advantage of it. To block most trackers, the extension is set by default and must work out of the box, but there are trackers that will slip from time to time.
To deal with them, you are going to enable some settings manually, such as Trekking protection In extension settings. Alternatively, you can also add your entries to the filter lists of the extension to block any new tracker.
Now, you probably noted that I have suggested two versions of Ublock origin in the header. This is because Google killed a large number of Google Chrome Extensions in early 2025 with its manifest V3 update. Google Chrome users can switch to Ublock Origin Lite instead, designed to work with the updated extension rules of Google Chrome.
Even if you are stuck in an inbox throughout the day or keep on switching accounts, trackers will follow you. Thankfully, now it is much easier to block them, and it’s some clicks with the right extension.
