Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Hey, I've just found a great source of cartoons with dubbing in my native language, which I highly prefer than original dub. The source has many many cartoons I would like to download and preserve. However, the creator uploads them to filemoon. Ive tried using ytdlp, but it lists filemoon as piracy site and wont allow downloading. I can downlaod them one by one with live stream download extension or with the stream detector extensions but, as I mentioned, there is a great amount of episodes and links it will take a lot of time like that. Hence, my question regarding a tool that would allow me mass download from filemoon. Are you guys aware of any possibilities?
