I tried to download the the source files and debian files for source package agg, but Chrome blocked the downloads with this message on the error console:
The problem appears to be that the download links at the bottom of the source page
https://packages.debian.org/source/trixie/agg use http: instead of https:. Clicking on these insecure links results in a 307 temporary redirect to the corresponding secure link. Chrome seems to block secure pages with insecure links that redirect to secure locations. The source page should have secure links.
