Firefox Send, Mozilla’s free, encrypted file transfer service, is officially launching to the public today following its debut as a “Test Pilot” experiment back in August 2017. The service allows web users to share files up to 2.5 GB in size through the browser while protecting them with end-to-end encryption and a link that automatically expires to keep the shared files private.
When Mozilla first began testing the web-based Send tool, file shares were limited to 1GB. Today, that remains the limitation until users sign up for a free Firefox account. They can then opt to share files up to 2.5GB.
