Is it really? I mean, if I wanted to send a file to someone via Google's e-mail servers or a chat application like Facebook Messenger but wanted to make sure it didn't stick around for those two companies to data mine, this seems like it would do the trick.
From Mozilla's perspective, doing "one upload, one download" also kind of solves the problem of becoming a new "megaupload" for illegal content. Not the problem of the illegal content being there (since it's unsolvable), but the accountability of being the party responsible for spreading it around.
I've used this once or twice a week since it was announced a month or two back here on HN, and love it. It's my go-to way to send any file that's > 10MB.
I remember doing some mortgage applications last year and being frustrated that the built-in Zip encryption in Windows is weak/broken, and begging them to have a secure file upload feature.
With this, it's all set - as long as the recipient picks it up within 24 hours of course. 48 would be better but I'm not quibbling, I can always resend and if 24 is what they need to keep the service up, 24 it is.
This is simple and awesome and I appreciate everyone who worked on it.
