The extension is a straightforward unit converter new-tab replacement with no declared permissions, no network requests in JavaScript beyond a thank-you page redirect on install (:5-8) and a search form POST to [domain withheld] (the publisher's own domain). All JS is plain, unminified conversion math. The ML score of 0.66 was driven by generic structural features (innerHTML, appendChild, form tags, file counts) that appear in any UI-heavy extension, not by suspicious code patterns. The only notable context concern is that EZDev LLC has other extensions flagged malicious — a meaningful publisher signal — but this extension's code itself contains zero malicious behaviors; it makes no external API calls, performs no data collection, and has no obfuscation.
