∟Firefox Extension - Gmail S/MIME

This section describes the Firefox extension, Gmail S/MIME, which allows you to send/receive signed and encrypted emails in Gmail using Firefox.

If you are a Gmail user, you can install the Firefox extension "Gmail S/MIME", which allows you to send/receive signed and encrypted S/MIME messages in Gmail using Firefox.

Here are main steps to install "Gmail S/MIME" and use it on Firefox 3:

1. Obtain your personal certificate with private-public key pair from a trusted root CA.
2. Install your personal certificate with private-public key pair into Firefox 3.
3. Download and install the latest version of Firefox extension "Gmail S/MIME" from https://addons.mozilla.org/en-US/firefox/addon/592.
4. Log in to your Gmail account and create a new email message.
5. Click the "Sign" icon to add your digital signature to this new email message.
7. Click the "Send", Gmail will ask for the password if your personal certificate is password protected.

You can also click "Padlock" icon to encrypt any new email message.

I will add more tutorial example on Gmail S/MIME later.
