## Review summary

Users praise effective Yahoo Mail ad blocking and the developer’s prompt updates, with broad positive sentiment and cross‑browser support. However, reliability on Yahoo Mail is mixed, with ads reappearing after changes or the extension failing at times. Some raise privacy concerns, note redundancy with other blockers, or report regional availability issues.

- Some reviews report that it no longer works for Yahoo Mail
- Privacy concerns about the extension potentially accessing sensitive email data
- Potential redundancy if you already use another ad blocker (e.g., UBlock Origin)
- Availability/download access issues in certain regions (e.g., China)
