I've been building a fully featured CLI tool for Firefox Send, supporting this new release. For anyone that is interested: https://github.com/timvisee/ffsend

Thanks a lot. The first thought after seeing this was that I wish it had a CLI and I know I am lazy enough to never write one.

That was my assumption. Your comment took me a little by surprise actually because there's no actual need for the internet in SSH and in fact I probably do 90% of my SSHing on local networks. But I guess your usage differs significantly?

For desktops, yes, but my default assumption for a phone is that it's on a mobile network

A mobile network is still mostly a fallback "if there's nothing better available", and IIRC all current smartphones prefer a WiFi link over a mobile one (if one is up). Perhaps with 5G, we might get to the point where WiFi is too much hassle to set up...

In addition to NUMEROUS 3rd party tools, Google already provides a tool exactly like AirDrop for Android. It's a feature of the Files app https://play.google.com/store/apps/details?id=com.google.and... which has over 100M installs. Look at the 3rd screenshot. ENCRYPTED FILE SHARING Files’s offline file sharing is secured with WPA2 encryption, providing a more secure file transfer. Files app uses Bluetooth to set up e…

Does Files actually allow transfer with desktops or laptops? It sounds like it only transfers between Android devices.

It's not really necessary on a desktop or laptop., Unlike an iPhone, all you have to do to transfer to a desktop is plug in a USB cable. After that, you select to share your storage with the PC on your android phone and you can operate on it as if it were a USB drive or a digital camera. On an iPhone you have to install iTunes, log on, jump through a bunch of hoops, and then you only get access to a fraction of the phone's filesystem anyway.

Dozens of responses, and not one mention of Dropbox. Works perfectly for this exact purpose on Android.

You missed the "without going through the internet" part.

It does have a LAN sync mode...but it's supplemental at best. Plus, the clients need to bootstrap and authorize through the Internet first.

Yes. Tested on Chrome, Safari, and Edge.

Oddly, it doesn't work for me (FF 65.0.2, windows 7) -- I just get an inert white rectangle in the middle of the screen. I tried turning off ublock origin and DNT settings, but it still is just a rectangle. It works on chrome, and does not work on IE 11 (win 7 doesn't support edge)

This seems to be a known bug if you have used the old version of send in your profile that may be fixed now. If you try it in a private browsing window and it works, it's probably that bug.

Another neat feature actually built into Firefox is Take a Screenshot. To the right of the URL field, in the three dots menu. Option to save it locally, or save in the cloud with a URL with some expiration options. Sorta like a pastebin for screenshots. It only takes screenshots within the confines of a Firefox window.

Glad you like it (I worked on it). Just a side note, the cloud service will be going away in the future, but the ability to save it locally will remain.

Which is why you don’t host it on AWS. Wrong tool for the job.

Their Github page specifically mentions AWS S3 as a requirement. So they are using it.

It mentions "AWS S3 or compatible service". The S3 API is a de facto standard for object storage services, and there are numerous implementations of it.

Thanks for the info. Let me see if I understand this correctly. Browsers don't send the anchor tag (ie: with GET requests). FF Send takes advantage of this by using the anchor tag to store the key for decryption. That is kinda novel. You still need to trust the upload client to not leak the key, but I see that you've written a CLI version. Interesting! Thanks for the response.

You got it! The only thing you'd have to worry about is malicious JavaScript on the Firefox Send website which I believe would be highly unlikely. And of course, you must keep your link secret. Yes, such a CLI tool would help protect you against a MITM with malicious JavaScript.

Unlikely but possible. Two words: browser extensions.
