Mozilla has launched a bunch of simple experimental tools for its in-house browser Firefox, under its Test Pilot segment. Now what is Test Pilot? It is a Firefox add-on which would let you test all the new tools that Mozilla develops (or is developing) for Firefox, and are still under the experimental/conceptual phase. One such simple tool under the Firefox Test Pilot program is Firefox Send.

In simple words, Send is a tool that would let you send large files (upto 1GB) to another person, over a web link. Well I can do the same with sendanywhere also, right? Yes, you can. But here is how Firefox Send is different. Its secure, rather very secure and absolutely free.

In the current version, you can securely send files to a contact using a link (that also contains an encryption key) that only works once. The encrypted file, which is stored on Mozilla’s server, is destroyed immediately after it has been downloaded once or after 24 hours have elapsed.

Mozilla claims that unlike the other experimental tools of Test Pilot, Send doesn’t require any add-on, but can be used as a simple web application on any modern day browser. All you have to do is select and upload the file, and share the link with whoever you want to share the file with. You don’t have to worry because your file isn’t stored on Mozilla’s server, and neither would it stay on the internet forever. Firefox Send uses WebCrypto API with the AES-GCM algorithm to encrypt and decrypt the file in the browser, meaning the file that’s transferred to Mozilla’s server is already encrypted and its contents can’t be viewed by Mozilla, though it does receive the filename and file size.

Thought the tool is still under development phase, the service works with Mozilla Firefox 54 and Google Chrome, but doesn’t yet play nice with Apple Safari or Microsoft Edge. I tried using the service on Edge, was able to access the web application but couldn’t really upload any file. Though it successfully worked on Chrome. So I suppose, Mozilla is working on a couple of browsers as of now.

Why don’t you go ahead and try Sending something once, and let us know how it works out for you.

    Great, but there are many online services which can do this and you can send even more. For example with MyAirBridge, you can send up to 20 GB for free, without registration and with the highest encryption possible during the transfer.
