I'm unable to update Mozilla Firefox using apt due to the following error:

E: Failed to fetch https://packages.mozilla.org/apt/dists/mozilla/main/binary-amd64/Packages 400 Bad Request [IP: 34.160.78.70 443]

While troubleshooting, I found that the request does return the package list, but with a 400 Bad Request status, which causes apt to fail.
