Once the download and the installation has fully completed, you'll need to activate this language for the Mozilla Firefox user interface.
To activate the new language:
* Close all Mozilla Firefox windows
* Restart the program from the command line, adding the following switches:
MozillaFirefox -UILocale es-ES -contentLocale ES
* The user interface should be in your favourite language
The locale codes are shown in the previous page, beside each localization project information.
I don't know how to for Mozilla Suite......
