Top Risks

  • Privacy policy is Google's generic account policy — not scoped to this extension, yet admits data collection and third-party sharing.
  • Extension has not been updated in 27 months (zombie-tier staleness).
  • No developer display name; only email at personal domain reduces accountability.
  • No CSP declared (MV3 default mitigates but no explicit policy).
  • Moderate 3.7 rating with 20k installs warrants review.

Evidence

  • privacy_policy_generic store Policy URL is myaccount.google.com — not extension-scoped; admits data_collection=true, third_party_sharing=true.
  • maintenance_stale store Last updated March 2024; 27 months since update triggers +8.5 maintenance score.
  • verified_publisher store Verified publisher badge present; -3.0 reputation discount applied but capped at -1.0 due to stale >18mo (0c).
  • no_developer_name store developer_name is empty string; only email ds@dannyadam.com available.
  • no_cve_findings crx cve_findings_raw is empty; CVE pillar = 0.
  • no_code_findings crx code_findings_raw empty, obfuscation_score=0.0; code quality pillar = 0.
  • operator_cluster_clean api sibling_count=0; no sibling extensions under same fingerprint.
  • installs_medium store 20,000 installs; +1.0 webstore signal applied.

Permissions Breakdown

  • activeTab low Only accesses tab on user action; limited scope.
  • contextMenus low Adds right-click menu items; no data exfil surface.
  • scripting medium Can inject scripts into active tab; moderate capability.
  • storage low Local preference storage; no exfil risk alone.
