Is Turn Off the Lights for Firefox safe?

Turn Off the Lights for Firefox dims video backgrounds and injects night-mode styles across all pages, with a link-click handler that lets any visited page overwrite the extension's color settings.

The extension is a video-dimming utility that darkens the area around embedded video players and applies customizable night-mode colors to every page you visit. Its content script runs on all URLs and listens for anchor clicks using the turnoffthelights:// scheme, which — if triggered by a link on any page — writes color values directly to chrome.storage.sync without verifying the page's origin. No user data is collected or transmitted externally.
