RPi 2 - Raspbian Jessie
I installed IceWeasel a few days ago. It works well enough, but it's based on Firefox 38 which is pretty outdated and doesn't support certain add-ons. Apparently, IceWeasel is no longer being developed, and the official Firefox is now the thing to use.
I found the http://mozilla.debian.net/ site and added "deb http://mozilla.debian.net/ jessie-backports firefox-release" to my sources.list file. However, when I do an apt-get update I get "Failed to fetch http://mozilla.debian.net/dists/jessie- ... f/Packages 404 Not Found".
So, is there just not a suitable Firefox version for the Pi yet, am I using the wrong source?
Any help would be appreciated. Thanks!
