Video Timestamp Keeper από Shibigami

Video Timestamp Keeper remembers exactly where you left off in any HTML5 video or audio and automatically resumes it after a reload, tab close, or browser restart — no account, no history required.

Ever lost your place in a long lecture, podcast, tutorial, or movie because a page reloaded or your browser crashed? This extension quietly saves your playback position as you watch and puts you right back where you were the next time you open the page.

Features: • Automatic save & resume for video and audio on virtually any website • Survives reloads, tab closes, and full browser restarts • Skips ads (won't save or restore an ad's position) and handles pre-roll ads • Popup list of everything you've saved, with progress bars — jump back to any of them in one click • Organize saved videos into custom playlists • Adjustable thresholds (minimum position, "finished" cutoff) and auto-cleanup of old entries • Works offline; your data stays in your browser

Includes a 30-minute free trial so you can try the full experience before purchasing.
