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

Note that the decompression duration of a xz archive is slightly the
same that a gzip archive.

Title:
thunderbird deb archives should use lzma compression
Status in “thunderbird” package in Ubuntu:
Opinion
Bug description:
Anyway, thunderbird requires ~256MB of free memory during operation.
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.
