Demo pages with screenshots or charts, shared on a demo site behind a login such as Cloudflare Access, showed only the images' alt texts in Firefox, and no styling. Firefox does not send the login's cookie from the sealed frame the page runs in, so the login answered in place of the images. Shared pages now carry their images, styles and scripts inside the page itself, so they look the same in every browser. Pages shared before can be brought up to date with "Share again".
