I'm watching this playlist and it has tens of clips that I can hardly watch at once.
The problem I have is that the next time I open the playlist, it starts from the clip #1.
How can I get YouTube to return to the last position of one playlist?
You might try this : https://addons.mozilla.org/en-us/firefox/addon/video-resumer/ it also exits for chrome
This Firefox extension does the job.:
Automatically resumes YouTube videos from where you played them last. Without this extension, for example, when you click through YouTube videos, back and forth, they always start from the beginning. No more. With this extension, previously seen videos will resume from where you left them at. Even if you restart your browser

Seeing as proper didn't add more info, added this to help others.
