The extension contains a single 21-line content script () that uses a MutationObserver to watch for tweets from non-followed users on [domain withheld] and hides them by setting `display:none`. There is no network activity, no data collection, no exfiltration, no eval, no remote code loading, and no use of sensitive APIs — just DOM manipulation entirely local to the page. The bundled manifest declares no permissions and restricts content script injection to `*://*.[domain withheld], which matches the extension's stated purpose exactly. The published manifest adds a `storage` permission not present in the bundled manifest, which is a minor discrepancy but not a security concern (storage is benign and the code doesn't even use it). The ML score of 0.74 is a clear false positive driven by the extension's tiny size (621 bytes, 5 files) and its content-script footprint, which superficially resembles malware patterns in feature space but is trivially benign on code inspection.
