This bug still occurs with 16.0.2+build1-0ubuntu0.12.10.1 version. Below you see that xz saves 19% of archive size compared to gzip : -------------- j@j-VB:~$ 7z l /var/cache/apt/archives/thunderbird_16.0.2+build1-0ubuntu0.12.10.1_amd64.deb | grep data Path = data.tar.gz Path = data.tar.gz ..... 49664000 22364697 data.tar j@j-VB:~$ 7z x /var/cache/apt/archives/thunderbird_16.0.2+build1-0ubuntu0.12.10.1_amd64.deb

I think that all thunderbird Debian packages should use lzma compression method in order to decrease their size. The parameters of the lzma compression should be choosed in order to require a maximum of ~256MB of free memory for decompression.
