>>105964405Learn to copy your browser's headers from network tools and import them into whatever download tool you need to use. It could be yt-dlp, streamlink, ffmpeg, or N_m3u8DL-RE if it needs to be decrypted like onlyfans stuff. It can be as easy as copying the m3u8 link and pasting it into yt-dlp like it was a YouTube link and as hard as needing to mimic every single header from your browser, or worse needing to set up a CDM for decryption. If it's a single file like mp4 rather than m3u8 or some shit you can also try copying the curl command from network tools in your browser and adding -O filename.mp4 on the end to download it.
