To decrypt a message you receive, simply view it and Mozilla will prompt for your GnuPG passphrase.

Your Mail & Newsgroups window also has a new Enigmail menu. Explore both menus where you'll find numerous useful options and utilities: generating new GnuPG keys, setting default behavior, viewing the actual gpg commands invoked, and more.
