Mozilla Firefox Send lets you share encrypted files privately and for free


Now, the tool has its own website, which lets you easily send files up to 2.5GB in size (with an account) to your friends, colleagues, or anybody else. You can try out Firefox Send here. Firefox Send offers various controls and features, such as the ability to limit how many times the file can be downloaded before it expires. You can choose when your file link expires, the number of downloads, and whether to add an optional password for an extra layer of security.

Given that the files are encrypted and aren't stored, however, it's going to be ruddy hard for anyone to find out what you've sent anyway.

The browser maker just launched Firefox Send, a free encrypted file-transfer service. The maximum for both being 100 downloads and seven days, respectively. Only the sender has access to the files and the intended receiver of the files, who will be able to decrypt the files automatically when they finish downloading.

The service is billed as a simple - and free - way to send large files. While there are already plenty of online storage provider out there but Send might be something you want to consider if you want to share some files without having them permanently stored online.

The service uses an algorithm known as AES-GCM-128 to encrypt and authenticate data on the sender's computer before uploading it to Mozilla servers. 'Sending files over the internet is something many of us do everyday.

The impermanence of the files is part of the security and privacy pitch as well, and Mozilla says this is something that differentiates Firefox Send from Dropbox, iCloud, OneDrive, or Google Drive. An Android app is expected to launch in beta this week. "As with all Firefox apps and services, Send is Private By Design, meaning all of your files are protected and we stand by our mission to handle your data privately and securely". Despite the branding, Firefox Send works with any browser.
