Why this file encryption service is safer than sending email attachments

Firefox Send is a great way to send files to anyone quickly, safely, and securely. Using file encryption and password protection, Firefox Send, lets you share files of 1GB to 2.5GB through a secure link you send to recipients.

Here's how to use the Firefox Send service.

In July 2020, Mozilla announced it was temporarily suspending Firefox Send due to malware abuse reports. Mozilla will be adding a mechanism for reporting abuse.

How Firefox Send Works

To use Firefox Send, you'll need to sign up for a Firefox account, which is the same account you use with Firefox Sync.

Firefox Send is often a better choice than email because of its ability to handle larger file sizes as well as its security features.

  1. Sign in to your Firefox account.
