History
On August 1, 2017, Mozilla launched Firefox Send via its Test Pilot program. The developers wanted to experiment with end-to-end encrypted data syncing and this service allowed them to try out encrypting large files, gigabytes in size, as opposed to the megabytes usually synced by browsers.
Firefox Send was launched to the public on March 12, 2019.
On July 7, 2020, the service was suspended after the discovery that
