Twitch DVR player
Never miss an exciting moment again with Twitch DVR (not actually affiliated with Twitch in any way). Replace the standard Twitch player with one that supports rewinding to any point in the stream! Jump back and forth between live and previous content. Installing the extension will automatically replace the Twitch player with a player that supports DVR. You can toggle between the DVR player and the regular Twitch player at any time.
