Use Ctrl + mouse wheel over an ordinary YouTube video to choose a comfortable pace. SmartPace learns one stable local sample from a meaningful manual viewing session. After three valid videos from the same channel, it silently reuses that channel's median pace on future videos.
Unknown channels remain untouched. Shorts and live streams are excluded. Profiles, settings, and optional JSON backups remain local to Firefox.
