Semi-related, but does anyone know if Firefox Send is on the chopping block? They took it down before the layoffs due to security concerns, and now I'm worried it won't be coming back online.
Every alternative I've been able to find has been either poor quality or too shady for me to ever actually want to use.
Not given priority right now - it's getting abused by malware authors. Confirmed via Mozilla IRC.
You can set it up yourself really easily (got it running locally on Mac in 5 mins), throw an auth'd gateway in front of it to keep it away from bad actors: https://github.com/mozilla/send
I don't know if Mozilla plans to bring it back but I know the solution is just around the corner: host it yourself. If you only want to do things like this you could use any SBC - Raspberry Pi etc - running some distribution of some operating system you prefer - Linux, *BSD, etc - hanging off your own internet connection. Either run something cloudy - Nextcloud, Owncloud, Syncthing, Seafile - or find (or make) a program made for this purpose. Get a domain name, use dynamic DNS to keep that name pointing at your IP and you're done - welcome to the world of self-hosted services.
Now that you've made a start you'll probably find you start adding services to that box under the stairs. Why pay for Dropbox when you can use your very own box with far more storage for far less money? Run something like Airsonic and you can stream your own media. Instead of having Xi Jinping watching your goldfish through that IP camera you can put the thing in a dedicated network zone, run a VPN on the box and make the camera only accessible through that VPN. The possibilities are close to endless, the costs are low and coming down all the time, power consumption can be negligible if you choose the right hardware. If in the end you don't like running your own services you can always use something run by someone else so why not give it a try...
...as is shown time and time again when some commercial entity fesses up to having lost a few TB of user data, Canon being the latest (?) example of such.
If you have family or friends you can make a deal with them: you get to hang a backup storage device off their network, they get to do the same on your network. Send encrypted backups and your data should be safe, and so should theirs. Problem solved, everyone happy and nobody gets to mine your data.
We as a family run a bunch of Synology NASes and back-up to each other (with different households we get geographical distribution). Running Synology-provided apps Drive (syncing and backing up computers to NAS), Hyperbackup (backing up from one NAS to another) and Moments (takes care of photos from cellphones) has been very simple and does everything we need.
All that just for few hundreds of euros; all data are private and nobody is trying to constantly upsell or trying to figure out how to monetize something taken for granted until now.
I've tried many of the options, and Croc [0] has always worked best for me. I tried Firefox Send, but the downsides were that the entire file had to finish uploading first and a lack of auto-resume.
