Extension Security Checker - Chrome Permission Scanner

Extension Security Checker helps Chrome users understand the security signals behind their installed browser extensions. Many extensions request permissions such as tabs, cookies, history, webRequest, scripting, or all-site access. These permissions can be legitimate, but they may also expose sensitive browser activity when used by untrusted or over-permissioned extensions. This extension scans installed Chrome extensions locally, explains technical permissions in plain language, highlights sensitive access, and shows which extensions may deserve closer review. Core features: - Scan installed Chrome extensions locally - Explain extension permissions in plain language - Highlight sensitive permissions and all-site access - Identify unusual install sources - Compare with the previous local scan to show permission or extension changes - Export a local JSON report - Support English, Chinese, Japanese, and French Important note: Extension Security Checker is not antivirus software and does not claim that an extension is safe or malicious. It provides permission risk explanations and review signals to help users make informed decisions.
