After this, Firefox will be restarted in the new selected user interface language.

In the options for the Simple Locale Switcher, you can choose whether you want to display the FTP or HTTP version of the Firefox page containing the list of language packs. You can also choose if you want the language tag to appear in the Firefox toolbar.
