There are Linux builds of Firefox Aurora available on Mozilla. But if you’re on Debian testing (or like to live dangerously with unstable) and prefer installing/updating via APT, then you’d might want to install Iceweasel Aurora.
I’m on Debian testing and this is what I did:
- Run apt-get install debian-keyring and apt-get install pkg-mozilla-archive-keyring (so that APT has signed keys and won’t whine when you update)
- Edit the file
/etc/apt/sources.list
and stick in this linedeb http://mozilla.debian.net/ experimental iceweasel-aurora
- Run apt-get update, followed by apt-get install -t experimental iceweasel-aurora to install Iceweasel Aurora
For other builds of Iceweasel, you can get more instructions here.
