This extension calculates and displays the total duration of a YouTube Playlist
- This extension works with any number of videos
- You can set the index of starting and ending video and get duration of those videos.
- Also works on mobile
Refresh the page after installing the extension.
If the number of videos in a playlist are more than 100, just scroll down to get complete duration.(As most of the time, YouTube renders only 100 videos for the first time page loads.)
