5:T46e,PixelBlock's current Chrome Web Store listing describes a focused Gmail extension that blocks email tracking attempts and shows a red eye when it finds and blocks one. The listing records version 2025.12.01, updated December 1, 2025. Mailshade 1.1.0 targets a broader workflow: six opt-in webmail integrations, declarativeNetRequest rules for reviewed tracker endpoints, in-inbox detection, supported tracking-link warnings and local sender-level history. The PixelBlock listing does not link to a public source repository, while Mailshade makes source archives and checksums available; reviewers must match an archive to the exact tested package version. That is an auditability distinction, not efficacy evidence. Ratings and user counts change frequently and are deliberately excluded from the conclusion. The two pinned builds have not yet completed the same controlled fixtures, so claims about protection rate, link behavior, benign-image breakage or overall superiority remain pending. Gmail-only users may value PixelBlock's narrow interface, while people who use several webmail services may value Mailshade's declared scope.3:["$","article",null,{"className":"prose prose-ink max-w-none","children":[["$","h1",null,{"children":"Mailshade and PixelBlock compared"}],["$","p",null,{"className":"text-lg text-ink-200","children":"$5"}],["$","section",null,{"aria-labelledby":"comparison-record","className":"my-10 rounded-2xl border border-ink-500 bg-ink-800 p-6","children":[["$","div",null,{"className":"flex flex-wrap items-start justify-between gap-3","children":[["$","div",null,{"children":[["$","h2",null,{"id":"comparison-record","className":"m-0 text-xl","children":"Comparison record"}],["$","p",null,{"className":"mt-2 text-sm text-ink-200","children":["Facts reviewed on"," ",["$","time",null,{"dateTime":"2026-08-21","children":"2026-08-21"}],"."]}]]}],["$","span",null,{"className":"rounded-full px-3 py-1 text-xs font-semibold uppercase tracking-wide bg-ink-600 text-ink-100","children":["Result: ","pending"]}]]}],["$","dl",null,{"className":"mt-6 grid gap-5 md:grid-cols-2","children":[["$","div",null,{"children":[["$","dt",null,{"className":"text-sm font-semibold text-ink-100","children":"Test date"}],["$","dd",null,{"className":"mt-1 text-sm text-ink-200","children":"Not yet tested; no performance winner is claimed."}]]}],["$","div",null,{"children":[["$","dt",null,{"className":"text-sm font-semibold text-ink-100","children":"Methodology"}],["$","dd",null,{"className":"mt-1 text-sm text-ink-200","children":["$","a",null,{"href":"https://mailshade.org/guide/how-to-audit-an-email-tracker-blocker/","children":"Read the published method"}]}]]}]]}],["$","h3",null,{"className":"mt-7 text-base","children":"Versions in scope"}],["$","ul",null,{"className":"mt-3 grid gap-2 md:grid-cols-2","children":[["$","li","Mailshade-1.1.0",{"className":"text-sm","children":[["$","a",null,{"href":"https://chromewebstore.google.com/detail/mailshade/opdjbaphkkfkngiaafcdaommanebfamn","children":"Mailshade"}],": ","1.1.0",["$","span",null,{"className":"text-ink-300","children":[" — ","Current public Chrome Web Store version confirmed on 2026-08-19."]}]]}],["$","li","PixelBlock-2025.12.01",{"className":"text-sm","children":[["$","a",null,{"href":"https://chromewebstore.google.com/detail/pixelblock/jmpmfcjnflbcoidlgapblgpgbilinlem","children":"PixelBlock"}],": ","2025.12.01",null]}]]}],["$","h3",null,{"className":"mt-7 text-base","children":"Method and current result"}],["$","p",null,{"className":"mt-2 text-sm text-ink-200","children":"Each pinned extension must run in a clean Chrome profile against the same versioned pixel, link and benign-content fixtures before comparative performance is stated."}],["$","p",null,{"className":"mt-2 text-sm text-ink-200","children":"Current versions and publisher-stated scope are sourced, but no blocking-rate, false-positive or overall comparative result is claimed before the shared run."}],null,"$undefined","$L6","$L7","$L8","$L9","$La"]}],"$Lb","$Lc","$Ld"]}]
