Script Traffic Light 作者： Santiago

Script Traffic Light is a small privacy-oriented extension that controls whether websites can load network scripts.

Two controls in the popup:
• Default — applies to all sites
• This site — override for the current website (or inherit the default)

Modes:
• Red — block all network scripts
• Yellow — block external (third-party) scripts only
• Green — allow all scripts
• Gray (this site only) — use the default

How it works:
• Uses Manifest V3 and the declarativeNetRequest (DNR) API
• Only affects network script requests (not inline scripts or eval)
• Settings are stored locally in the browser (storage.local)
• No accounts, no analytics, no remote servers, no telemetry

Hostnames are normalized by stripping a leading "www." so www.example.com and example.com share the same site setting. Changing a mode saves immediately and reloads the current tab so the new policy applies.

This extension is intentionally minimal: no filter lists, no cloud sync, no tracking.
