Mozilla launches Firefox Send for private file sharing

Mozilla look to reclaim some ground from the all-powerful Chrome with a new way to send and receive files securely from inside the browser. Firefox Send first emerged in 2017, promising an easy way to send documents without fuss. The training wheels have now come off and Send is ready to go primetime. Will it catch on with the masses, or will only a small, niche group use it to play document tennis?

How does it work?

Firefox Send allows for files up to 1GB to be sent to others via any web browser (2.5GB if you sign in with a Firefox account). The files are encrypted after a key is generated, at which point a URL is created containing said key. You send this URL to the recipient, who is able to then download and access the file securely. Mozilla can’t access the key, as the JavaScript code powering things only runs locally.

Before sending, a number of security settings come into play. You can set the link expiration to include number of downloads, from one to 200, or number of days the link is live (up to seven). Passwords are also available for additional security.
