Haven't used it yet but it has endless possibilities, like sharing a hi-res flac file with a distant friend.

Firefox Send Is an Easy Way to Share Large Files Securely"You’ve got no shortage of ways to send encrypted messages, and at least as many cloud services for sending large files. But the Venn diagram for the two remains surprisingly, inconveniently small. That’s the beauty of Mozilla’s Firefox Send, a free, intuitive, web-based service that lets you share large encrypted files, no strings attached.
"Send began in 2017 as an experiment, part of Firefox’s since-discontinued Test Pilot program. Since then, it has languished in beta, gaining a few features along the way, but mostly in the shadows. Tuesday marks its public launch.
"What sets Send apart is its ease of use. It works in any browser; just go to send.firefox.com. Upload or drag and drop files, and Send will generate a link that you can set to expire after a certain number of downloads—up to 100—or a certain amount of time, ranging from five minutes to seven days. You can send up to 1 gigabyte, or up to 2.5GB if you sign in with a Firefox account. For comparison sake, SMS generally maxes out at 600 kilobytes. The biggest Gmail attachment you can send is 25 megabytes. Firefox Send offers orders of magnitude more room, enough to send a high-definition episode of Game of Thrones."
