MacOS上で問題があります

We know there is problems on MacOS, but as we haven't any Mac, this platform isn't officially supported yet (unless someone send us a free Mac (Intel arch.) :) ). If Firefox hang when you try to use FireGPG or use option, it's probably because you haven't set a correct gnupg's path. Use about:config and edit the string extensions.firegpg.gpg_path to set it.

This happend sometimes, we don't know why. It's related to the IPC library, but I cannot reproduce the problem yet.

It's a know problem, and we're waiting on FireFTP's authors to fix it: they're using an outdated version of the IPC library.

FireGPGはGnuPGを含んでいません。したがって、GnuPGを別途インストールする必要があります。GnuPGをダウンロードするための文書をご確認下さい。

Yes. Everything is anonymous, we only collect version installed and previous version of the installation. Please read this : http://blog.getfiregpg.org/2008/07/07/about-stats/ Notice there isn't anymore stats about the XpCom because it is used everytime.

Yes, sometime there is problem. Use OpenPGP/Mime, it's better and always works.

鍵/署名とは何ですか? どのようにしてFireGPGを何かの暗号化/署名に使用しますか?

Check documentation to read basic information about hows GnuPG works. FireGPG is only an interface, the base is excactly the same.
