In order to enlarge the number of users of the Mozilla, Firefox e Thunderbird applications, and for those who are not so confident with english language, i suggest the mozillaitalia.org site, where it's available the italian language for the programs.

Installation is very simple!

Note that Mozilla suite and other programs are all available in localized languages.

Now you haven't no more excuses!
