Features & Capabilities

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.

Is Script Traffic Light 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.

Script Traffic Light requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

Script Traffic Light is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
