PixelBlock – Gmail extension that blocks email open tracking

I thought this is completely pointless nowadays:<p>- Gmail USED to block images unless you do &quot;allow images&quot;<p>- Gmail changed to a system where gmail pre-fetches the images and runs them through safety checks.<p>- Gmail only does this check if you open the email.<p>- Even if you block the pixel, you only block the gmail cache of it. NOT the original.<p>Unless I misunderstand.

I could very well be wrong but I always thought that if you disable loading pictures by default, that tracking pixels would be blocked as well. Unless you click on &quot;Show Pictures&quot; that is.

Kinda scary to have a chrome extension that can read all of your email. Is the cure more dangerous than the disease?

Maybe it is because I&#x27;m on FF and not logged in, but other than the name &#x27;omar.w.qureshi&#x27; (I think he submitted this on HN) I don&#x27;t see any other info other than the 5 sentence privacy policy. I would be hesitant to install such black-box extension. Could OSS this, or is there a reason not to do so?

I know gmail does some image caching &#x2F; proxying.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=6898454" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=6898454</a><p>I guess the vector here is when you read an email versus where from &#x2F; using which device &#x2F; etc.

If you really care about gmail privacy (ha) you should also<p><pre><code> var matches = document.querySelectorAll(&#x27;a[href*=&quot;www.google.com&#x2F;url?q=&quot;]&#x27;); &#x2F;&#x2F; remove all google spying redirects for (var i = 0; i &lt; matches.length; i++) { if (&#x2F;^(https?:\&#x2F;\&#x2F;(www\.|encrypted\.)?google\.[^\&#x2F;]*)?\&#x2F;?url&#x2F;.test(matches[i])) { var match = &#x2F;[\?&amp;](url|q)=(.+?)&amp;&#x2F;.exec(matches[i]); if (match != null) { matches[i].href = unescape(match[2]); } } }</code></pre>

Tracking is just one of the many reasons why it should be considered common courtesy to communicate in plain text (and attachments if necessary).<p>My email based workflow and toolchain has been plaintext only for years and I think I&#x27;ve been better off for it. The recent <i>efail</i> vulnerability just made me shrug. Plain text mail is all around more reliable, more accessible, less obfuscated, more to the point by the nature of the medium, easier to implement [...].

Gmail and every other webmail vendor should block all of these by default. That would be a nice hit to all these &quot;new&quot; drip campaigns (aka personalized spam newsletters).

I&#x27;m stunned every time people try to get privacy with Google.<p>It&#x27;s Google! I wish I could make you understand but I probably can&#x27;t.... :(

I hope this hits the front page as I feel this is an essential extension for email privacy that many people are unaware of.

I don&#x27;t think having tracking pixel in gmail is a big thing. Almost every modern messaging system such as whatsapp has read receipts. Since gmail has image proxy, it doesn&#x27;t leak any information. And most modern email client doesn&#x27;t open remote image unless allowed explicitly.<p>PS: I have built <a href="https:&#x2F;&#x2F;www.mailtag.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.mailtag.io&#x2F;</a>

Love it. Would be great to see as a direct Gmail Add-On instead of a browser extension.

Could the tracking pixels not be blocked via a uBlock Origin filter list?

extremely beneficial extension, you&#x27;d be surprised how many marketing emails are tracking when you open the email
