GeoLock por MaZy

GeoLock is a Firefox extension that blocks or allows requests with per-page rules: geoip country, geosite category, sing-box rule-sets, domain regex, and IP ranges.

How it works

Every time a page loads something — a script, an image, an API call — GeoLock checks your rules and lets it through or stops it.

A rule pairs a source (the page making the request) with a destination (what it's loading). If both match, the rule fires with its action: allow or block.

Rules run top to bottom. The first match wins. If nothing matches, your default action applies.

Example rules:

• When on a US site, block resources resolving to non-US IPs
• Allow only known CDNs on a sensitive site
• Block all traffic between two countries with one isolate rule

Matchers

• geoip — country of the resolved IP (v2fly geoip.dat)
• geosite — domain category like google, category-ads-all (v2fly geosite.dat)
• rule-set — sing-box rule-set, binary .srs or JSON source format
• domain — regex against the hostname
• url — regex against the full URL
• ip — CIDR range, IPv4 or IPv6
• any — matches everything
• and / or / not — combine the above

Features

• Bidirectional rules — fire in both source↔destination directions
• Isolate rules — define one boundary (say, "US") and fire whenever traffic crosses it
• Data sources by URL — geoip/geosite databases and any number of named sing-box rule-sets, auto-updated on a schedule
• Remote configuration — fetch and apply your config from a URL
• Built-in rule tester, per-page block log with match traces
• Raw JSON editor, import/export, one-click reset
• In-memory DNS cache, no telemetry
