Private, encrypted, open-source file transfer. It used to be "Firefox Send", but Mozilla discovered people sent things Mozilla wanted no part of. So since it was open source, other people started running servers. I find it's super useful for transferring log files around the world.
@ericphelps I had heard of Firefox send but didn't know it got forked. I'll check this out.
