No more Debian's Jessie/stable's Firefox? :(

[PhiLLip Pi]

I just ran apt-get update and saw: "W: Failed to fetch 
http://mozilla.debian.net/dists/jessie-backports/Release  Unable to find 
expected entry 'firefox-release/binary-amd64/Packages' in Release file 
(Wrong sources.list entry or malformed file)"

According to http://mozilla.debian.net/, it says "Sorry, this version is 
not available." What happened? I am using "deb 
http://mozilla.debian.net/ jessie-backports firefox-release" line in my 
64-bit Debian stable/Jessie's /etc/apt/sources.list file.

Thank you in advance. :)
