Makes Firefox/Thunderbird as the default client on every startup.

You can control the behavior by following preferences:

// true => set default for all users on the computer (*require administrator permission)
user_pref("[email protected]", false);

// true => use Firefox for http, https, .xhtml, etc.
// false => use Firefox for http only
user_pref("[email protected]", false);

// 1 = Mail
// 2 = News
// 4 = Feed
// (1 + 2 + 4 = 7 = All)
user_pref("[email protected]", 1);

This is mainly designed for corporate-use.
