TheIntroDB от Pasithea

It uses TheIntroDB to know when to show skip buttons. After install you’re ready to go: open a supported (or generic) streaming page and the extension will try to show skip buttons when timestamps exist. Optionally, set your TheIntroDB API key in the popup to submit timestamps right from the extension and to see your pending submissions.

Supported sites

These sites have dedicated extractors for the best experience:

• Netflix
• HBO Max / Max
• HDrezka
• Apple TV+
• Paramount+
• Peacock
• Plex
• Prime Video

Plus any site where the page has a TMDB ID in the URL (e.g. /tv/12345/1/3, tmdb-tv-12345, /watch/12345, tmdb/12345) or where the media title is visible. For those, the extension uses a generic extractor that parses the URL and page (e.g. S01E03, 1x03, season/episode in path) to detect show, season, and episode. So many other streaming sites work without a custom extractor.
