Media URL Timestamper (resume playback) Firefox

Media URL Timestamper (resume playback)

By: Kestrel Add-on
Remember audio/video playback position for later resuming without cookies, storage or logging in by automatically timestamping the address. Compatible with Youtube, SoundCloud, Invidious and others.

Features & Capabilities

Don't lose your spot in long music sets, podcasts, talks/lectures and saved live streams. Conveniently get the media's current time and put it in the URL for later resuming, either manually or automatically at regular intervals. This timestamped URL, also known as a deep link, can then be handled by the browser's session, history, bookmarks, sync service, share services etc. Anywhere the link goes the timestamp conveniently goes with it.

Supported websites: Youtube, Twitch, Facebook, SoundCloud, DailyMotion, Vimeo, Crunchyroll, VK, Niconico, Aparat, Odysee (LBRY), Hearthis, Invidious, Piped, Librarian, PBS, PeerTube, Vidlii, CloudTube, Utreon.

Some of these websites already have resume capabilities but require cookies or local storage to be retained. Some also need you to be logged in with watch history enabled and have other requirements like video duration and time watched. Timestamping the URL is more flexible and reliable, allowing you to clear cookies, browse logged out or with watch history disabled, as well as permanently store and share the timestamped links.

Automatic mode applies the current timestamp every interval (default 60 seconds) for media content that exceeds the minimum duration (default 10 minutes) and the current time is not close to the start or end (default 120 seconds). Alternatively the timestamp can be applied manually by clicking the page action icon in the location bar. The page action has a context menu which allows clearing the timestamp and temporarily toggling automatic mode on and off for the current page.

This approach only works with direct media pages and not media embedded in other pages.

It was a nice add-on that served well in the past years. However, since YouTube player has its new layout, this add-on is causing massive lags. That happens when the automatic mode is enabled. Unless the author provides a fix, best to disable the automatic mode. Still, without that function, there is a question if the add-on is still worth to be kept.
