Ever since I updated the extension last week, a new Google Drive API authorisation tab opens every five minutes for the sync functionality. No matter how often I approve it, it still pops up.

Edit: Developer has responded that it will be resolved. In the meantime, I've turned off sync completely.

Не уверен, но похоже расширение майнит во время простоя именно в firefox, в chrome такого поведения не наблюдается. Благо есть Violentmonkey.

I am using this to enable a script that runs on Firefox at YouTube playlists to enable a download of the playlist items' details. It has worked flawlessly and I am well pleased.
