About this extension
YouTube™ Watched Marker allows you to mark YouTube videos as watched without having to sit through them manually.
- One-Click Marking: Adds "Mark as watched" to context menus and YouTube's native three-dot video menus.
- Automated Worker Window: Plays queued videos briefly in a dedicated, muted worker window near the end of the video to register playback.
- Channel Timeframe Scanner: Batch queue videos from any channel's Videos page between two selected dates.
- Queue Controls: Pause, resume, retry failed items, configure active queue limits, and customize worker window bounds.
- 100% Private: Runs entirely in your browser. No telemetry, no remote analytics, and zero data collection.
