Resume Videos 作者： SilverRabbit90

Automatically saves where you left off in any HTML5 video and resumes it next time — with a clean list, per-video pause, options, and site exclusions.

Full description:

ResumeVideo remembers your position in HTML5 videos and brings you back exactly where you stopped.

Key features:

Automatic saving of the current position for any <video> on a page, and automatic resume when you reopen it.
A popup list of saved videos, each showing the saved time, duration and when it was last updated.
Delete a single saved position, pause/resume capturing for a specific video, or clear everything at once.
Options panel: automatic resume on/off, "Resumed from…" notice on/off, days before automatic deletion, and a resume offset in milliseconds (start slightly before or after the saved point).
Excluded sites: turn the extension off on specific sites (e.g. services that already remember your position). A few common sites are pre-listed but none is excluded by default; you can add your own.
Smart identification: on players that use changing links (blob/streaming), the video is matched by the stable numeric ID in the URL, so resume keeps working across sessions.

Privacy: all data is stored locally in your browser (storage.local). Nothing is collected, sent, or shared. There are no accounts, trackers, or external servers.
