This is a super cool new product from Mozilla.
It's called Send.
Upload anything up to 1GB in size, send the link to someone and as soon as they download it, the file disappears. One download and it's wiped. Gone! Poof! No more giant attachments clogging up email.
Data hygiene!
Encryption!
No login or registration required (or even possible).
Bookmark the site for the next time you want to send someone a crazy little video you made, but you don't want it hanging around on the internet either.
