I'm a day late to the news, but am just learning about Firefox Send, a free encrypted file transfer service launched by Mozilla.

Here is their Press Release with some more information. Here are the major features, as described in their release:

• Free
• End-to-End Encryption
• Security controls (download limits and expiration)
• Send files up to 2.5GB

It's open-source on GitHub under the Mozilla Public License 2.0.

There's also already a CLI tool to allow you to upload and get a link directly from the command line.

What do people think?
