Fanbox Zip Downloader от NONAME.period

Fanbox Zip Downloader adds a blue Download button to every FANBOX post page. Click it and the post's images, attachments, and text get bundled into one ZIP, with a live progress bar right on the button.

This is an unofficial fork of tana3n/fanbox-downloader — all credit for the original download logic goes to tana3n. This version simplifies it to one click: no options page, everything just works.
