Battery depleter. – Umbra - Ad Blocker for Safari Browser, Best Free Content & Ads Block Extension Review

Installed and set up one evening. Went to bed with 100% battery...woke up with 65%. Battery normally stays at 100% until morning. Looked at battery usage...35% dedicated to Safari browser. Promptly uninstalled Umbra.
