Detect and alert on malicious browser extensions A Chrome extension that scans your installed browser extensions and flags potential security risks. Features: ◾️Permission analysis — Detects dangerous and sensitive permissions (webRequestBlocking, debugger, cookies, clipboardRead, etc.) and broad host access patterns (, *://*/*). ◾️Install type checks — Flags sideloaded and developer-mode extensions that weren't installed from the Chrome Web Store. ◾️Malicious ID blocklist — Cross-references each extension against a bundled list of known malicious extension IDs. Matches are tagged with a BLOCKLISTED badge and the specific reason. ◾️Risk scoring — Each extension receives a composite score and is categorized as Safe, Warning, or Danger. ◾️Auto-updating blocklist — the extension can fetch the latest blocklist at scan time with a local fallback.
