Sobre esta extensión
Voidly Censorship Monitor turns your browser into a measurement point for open
internet-censorship research.
Every 15 minutes it tests 20 sites from a fixed, published list of 62 — news
outlets, social platforms, messaging apps and privacy tools that are blocked in
some countries — and records whether each one loaded from your network.
WHAT MAKES THIS VERSION DIFFERENT
Earlier versions reported a site as blocked whenever a request failed. That
cannot tell real interference apart from a domain that no longer exists, a
captive portal, or a local content blocker — and it produces a great many false
positives.
This version reads real HTTP responses and checks an independent public DNS
resolver before reporting anything:
• A site nobody can resolve is recorded as a dead domain, not as censorship
• A bot-check page is recorded as reachable, because the path is open
• A result the extension cannot stand behind is discarded rather than sent
PRIVACY
• No browsing history. There is no content script, no tabs permission and no
history access
• Your cookies are never attached to a test
• Permissions are an explicit list of the sites being tested, not wildcards
• Nothing is collected beyond the outcome of the extension's own scheduled tests
Works on Firefox for desktop and Firefox for Android.
Free, and free of charge — no account, no sign-in, no payment.
