The extension is a well-established character converter with 70k+ users and good rating. Source code shows only local dictionary loading (fetch from extension files) and no external network requests or data collection. The 'downloads' permission is present in the manifest but unused in code, and a manifest version mismatch exists between the bundled (v2) and published (v3, with additional 'tabs' permission); however, these do not indicate malicious intent. The ML model’s high-risk flag is based on standard DOM manipulation patterns and overly broad permission signals common in benign extensions.
