What should I do?
A langpack is a Firefox add-on containing information to see the GUI in a specific language. Every langpack uses a code for its language, and in Firefox 1.5 and above versions the code schema follows the RFC 3066.
The Italian version of Firefox, for example, uses the it code, a short for it-IT (the Italian language spoken in Italy).
For a language similar to North-Western Lombard (or Insubric), we worked out roa-IT-ins, referred to a Romance language (roa, SIL code), spoken in Italy (IT), and named ins (invented for our langpack).

This is the general way to use the langpack:
- Take an official version of Firefox (the Italian version, for example, uses the it code) and install the langpack (roa-IT-ins code).
- After that, there will be two available languages. When you start Firefox, you tell it to use the language with the roa-IT-ins code, and that's all.
You can use any official version
You can use any official version of Firefox (in English, French, Italian, etc.), but the langpack hard-codes the it code in a subset of the configuration preferences containing the URLs used for the interaction with the Mozilla servers.
