Features & Capabilities

ProofScout is a privacy-first page assistant that helps people inspect online opportunities and diagnose website problems without leaving the page they are viewing.

Tap the floating ProofScout button to access three tools:

Opportunity Inspector

Checks visible page wording for suspicious upfront fees, prize-release payments, requests for passwords or one-time codes, artificial urgency, guaranteed outcomes, private-agent pressure and contradictory “free entry” claims. Every finding includes a clear explanation rather than an unexplained score.

URL Inspector

Examines the current address for unencrypted connections, encoded or look-alike domains, raw IP addresses, unusually deep subdomains, excessive hyphens, suspicious trust words and unusual network ports.

Bug Doctor

Diagnoses broken images, insecure forms and resources, duplicate element IDs, missing labels, unnamed buttons and links, unsafe new-tab links, skipped heading levels, missing page-language declarations and missing mobile viewport settings. ProofScout can highlight affected elements directly on the page.

Users can also ask ProofScout to read the result aloud using browser speech synthesis. Voice commands are available when supported by the browser.

All inspection happens locally on the user’s device. ProofScout does not upload page text, browsing history, URLs or inspection results. It has no account system, advertising, analytics, remote AI service or page-content server.

ProofScout is a screening and development aid. It does not guarantee that a website is legitimate, secure or free from bugs.

Is ProofScout Page Assistant 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.

ProofScout Page Assistant requires a few sensitive permissions. 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.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

ProofScout Page Assistant is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
  • High **** ********* *** ******** ****** *** ********** *** *** ** ****** ** *****
