Firefox end is a free end-to-end encrypted file sharing - Service of Mozilla . The service has been temporarily unavailable since July 8, 2020 .

use

Firefox Send supports unannounced files up to 1 GB in size . If you log in with a Firefox account , the limit is 2.5 GB. However, regardless of the file size, an account is never required to download a file.

The files are deleted either after 5 minutes or 1 hour or 24 hours or 7 days or after a certain number of downloads . The user can specify this when uploading .

Technical implementation

Firefox send is written in JavaScript and runs for Node.js . The source code is available on GitHub .

Encryption

The Web Crypto API is used for encryption . A random private key is generated before the file is uploaded , which is used to encrypt the file and metadata before uploading. The server then returns a URL pointing to the encrypted data. The private key is added to the URL as a fragment identifier and presented to the user. With the URL and the fragment identifier you can now download the files from the server in a similar manner. So the private key is never sent to the server.

In addition, the file can be protected by a password .
