YouLikedIt от AnimeGif

This is the Firefox version of my Chrome extension with the same name: https://chromewebstore.google.com/detail/youlikedit/bejfebpalgeekbjobedlffdcaoohehic

YouTube often "forgets" about your watch history. After a couple years, it starts recommending videos you have already seen.

However, YouTube keeps track of videos you have LIKED/DISLIKED.

This extension automatically LIKES every single video that you configure it to like based on type:
- Simple
- Playlist
- Queue
- My Mix
