privacy_ext: Can not be installed since v4.0.1 not compatible)

[Joerg Kohne]

Hi,

Icecat is installed using Ubuntu 10.4 Repository (icecat, icecat-de).
"http://ppa.launchpad.net/gnuzilla-team/ppa/ubuntu maverick main"
(binary and source)

An installation is not possible (==> not compatible).
"http://ftp.gnu.org/gnu/gnuzilla/4.0.1/privacy_ext.xpi";

Should I better remove the Ubuntu repository and install via
gnu.org-sources? (manually installation)

OS is currently Trisquel 4.5 (based on Ubuntu 10.4)
(gNewSense is favored, but is too out of date, so I use Trisquel).

What is the best approach?

Thanks for response.

Joerg
