finding a more efficient way to download comics

hey im currently downloading some comics using a browser extension, but unfortunately im kind of losing my mind downloading hundreds of issues one by one. if anyone knows a way to make this faster and less mind numbing, id love to know. of course id prefer if it'd download the comics in cbz format, but i dont mind if it can only be in pdf or another file format. i can always convert it to my preferences

if anyone has any information feel free to send me a friend request and then dm me once i accept. thanks in advance
