What our analysis found
YouTube Speed Controls, used by 50,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in November 2025.
Analyst notes
The extension's code is fully transparent: it only adds keyboard shortcuts to control YouTube playback speed and displays a non-intrusive speed indicator. No network requests, data collection, or external resource loading occurs. The ML model's low score (0.04) and the pattern counts (e.g., js_appendchild, js_exclamation) are entirely explained by the extension's benign DOM manipulation and animation logic. The publisher is Google-verified and the extension has a clear purpose matching its description.
