Features & Capabilities

SUP (Super Ultimate Privacy) is a high-performance privacy extension designed to shield your online identity, block intrusive telemetry, and prevent cross-site tracking without breaking website layouts or functionality.

Built with a zero-data-collection philosophy, all processing occurs locally on your browser.

Key Features:

• Declarative Net Request (DNR) Blocker: Intercepts and blocks tracking domains, intrusive analytics scripts, and third-party trackers (Google Analytics, Facebook Pixel, Hotjar, Mixpanel, and more) at the network level.

• Non-Destructive Anti-Canvas Fingerprinting: Dynamically introduces subtle, offscreen noise into Canvas rendering methods (getImageData, toDataURL, toBlob), disrupting visual fingerprinting without breaking site UI, image editors, or QR code generators.

• WebGL & Hardware Masking: Spoofs WebGL GPU vendor/renderer strings via extension proxies while restricting system hardware enumeration (hardwareConcurrency, deviceMemory).

• Audio & Timezone Spoofing: Adds micro-scale random noise to AudioBuffer APIs to counter acoustic fingerprinting and normalizes the browser timezone output to UTC.

• WebRTC Leak Guard: Restricts non-proxied UDP traffic to prevent real local and public IP address leaks without impairing video conferencing services like Discord or Google Meet.

• Header Hardening: Automatically injects Do Not Track (DNT: 1) and Global Privacy Control (Sec-GPC: 1) headers alongside security enforcement headers (X-Content-Type-Options: nosniff, X-Frame-Options: SAMEORIGIN).

• Browser Hardening: Automatically disables network prediction, DNS prefetching, and hyperlink auditing (<a ping>).

Is SUP - Super Ultimate Privacy 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.

SUP - Super Ultimate Privacy requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

SUP - Super Ultimate Privacy is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
