Extension Permission Monitor

Audit installed extension permissions, track changes, and safely disable tools you no longer use — all locally in your browser.

Do you know what your Chrome extensions can actually access? Most people don't. Extension Permission Monitor scans your installed extensions, explains sensitive permissions in plain English, and shows you which ones deserve a second look — all without sending your data anywhere. Free features: - Local scan of all installed extensions with one click - Permissions explained in plain language — no cryptic API names - Heuristic review priority based on access breadth and capabilities - Enable or disable extensions with a confirmation step and undo action - 24-hour scan history stored locally - Search, filter, and sort by priority, status, or permission count - Your extension list never leaves your device - 7-day scan history and before/after trend comparison - Permission change monitor — know when an extension gains or loses permissions - Extension timeline — first seen, removed, enabled, disabled, and version events - Duplicate extension detector — spot overlapping tools you may not need both of - Detailed cleanup recommendations ranked by risk - Private notes and custom categories saved locally per extension - CSV export, JSON backup and restore, and a printable HTML report Accuracy note: Chrome does not expose reliable per-extension CPU or RAM usage. Review priority, activity estimates, and permission posture values are heuristic signals — not exact performance measurements or claims that any extension is safe or malicious. This tool helps you decide what to review; it does not make decisions for you.
