16:T4e7,Gblock 0.4.0 is a Gmail-focused commercial product with a broader advertised feature set than the previous version of this page acknowledged. Its Chrome Web Store listing says it blocks tracking pixels, strips known tracking parameters, follows tracked links through a proxy to mask the user's IP address, and reports newly detected trackers to its server so future messages can be blocked. The listing offers a 30-day free trial and then requires a paid subscription. Mailshade 1.1.0 instead declares six opt-in webmail integrations, blocks requests to reviewed tracker endpoints through Chrome declarativeNetRequest, handles supported tracking redirects locally with a direct-or-original choice, and keeps detection history locally for sender-level reports. Mailshade also makes AGPL-3.0-or-later source archives and checksums available; reviewers must match an archive to the exact tested package version. These are materially different architectures: Gblock advertises a proxy and server-assisted tracker discovery, while Mailshade emphasizes local processing and broader webmail scope. Neither architecture is automatically superior. Comparative efficacy, latency, false positives and privacy behavior remain pending a shared test and network review.11:["$","p",null,{"className":"text-lg text-ink-200","children":"$16"}]
