I am pleased to announce the new version of the GNU IceCat web browser.
GNU IceCat is the GNU version of the Mozilla Firefox browser.
This new version includes all changes made upstream in Firefox 3.6.11.
It is available for download here:
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … 86.tar.bz2
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … 686.tar.xz
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … 11.tar.bz2
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … .11.tar.xz
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/privacy_ext.xpi
and the GPG detached signatures using the key C03363F4:
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … ar.bz2.sig
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … tar.xz.sig
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … ar.bz2.sig
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/i … tar.xz.sig
ftp://ftp.gnu.org/gnu/gnuzilla/3.6.11/p … xt.xpi.sig
To reduce load on the main server, you can use this redirector service
which automatically redirects you to a mirror:
ftpmirror.gnu.org/gnuzilla/3.6.1 … 86.tar.bz2
ftpmirror.gnu.org/gnuzilla/3.6.1 … 686.tar.xz
ftpmirror.gnu.org/gnuzilla/3.6.1 … 11.tar.bz2
ftpmirror.gnu.org/gnuzilla/3.6.1 … .11.tar.xz
ftpmirror.gnu.org/gnuzilla/3.6.1 … cy_ext.xpi
