Pot Player For Youtube Integration (Links in Description)
Pot Player official page : https://potplayer.daum.net/
Firefox add on page : https://addons.mozilla.org/en-US/fire...
The skin that I use for pot player : https://mega.nz/file/NuxTzahA#vr4VnAl...
Alternative method : If above doesn't work for some reason. You can use this add-on https://addons.mozilla.org/en-US/fire... which adds an export button above the playlist.After installing the add-on,go to a youtube page which has a playlist. Press that "export" button which copies the video links to clipboard.Open Pot player, press "CTRL + U" . Check "auto paste Urls from clipboard" option. For the first time you may need to paste the Urls manually but after restarting pot player that autopasting feature shall work after pressing "CTRL + U" .
