Works great But I have troubles with the automatic loading of the next page when I use the 'right-click/Add page to playlist' option, rather than the Ctrl-Alt-A or the 'Add current page' button of the pop-up... Also, I cannot find where to customise the shortcuts...
Thank you for your feedback, I will look into it. To change the shorcuts, refer to this page: https://support.mozilla.org/en-US/kb/manage-extension-shortcuts-firefox
