Not really a mail client, and not really a part of your browser either – Simple Mail wants to be the lightweight e-mail client you thought you always wanted but never thought you could have. The Simple Mail extension allows you to write, read and get notified about message from inside of Firefox.
Some of the features include:
- Color coded messages
- Can set to “download headers only”
- Delete messages from the server
- Address book
If you are used to using a heavy duty e-mail client, this might not be the addon for you. If mail management isn’t that important to your day to day life and you just need an easy way of checking it, then Simple Mail is the client for you.
