Gokapi: Lightweight selfhosted Firefox Send alternative with AWS S3 support

Apparently Thunderbird are working on reviving Firefox Send and adding encryption.

Overall Thunderbird seem to be doing white well from themselves since rejoining Mozilla: >$8m in donations last year I think.

I just discovered this TH feature the other day when attaching a file to a mail but it looks like it works with plugins now, so you can use different providers.

Actually I came here to ask if Gokapi works with that Thunderbird feature.

FF Send already had encryption -- IIRC, Mozilla shut it down because it was being abused.

Abused in what way? Content? How would they know, if it was encrypted. Or volume?

Likely law enforcement found out about it being used to distribute illegal content and then applied pressure. Companies don’t have a strong history of successfully resisting that pressure.

law enforcement is so bass-ackward on privacy/security tools

Of course, if a hammer is for sale, some will use it to build houses and a subset will use it to hurt people. Just because something can possibly be bad doesn't mean we shouldn't have it

But if law enforcement’s data suggests to Mozilla that something like 60%+ of Send’s uses are for malicious purposes, what benefit do they have in continuing to make it available?

I’m all for privacy, but I wouldn’t support my tool being used predominantly for criminal activity, no matter how good I feel about it as a security/privacy tool.

Take down requests for DMCA and/or LEO for CSAM. Even though it is impossible for the server operator to know that material is on the server, the URLs + decryption passwords are shared with someone or a group -- if that is discovered by law enforcement or rights holders, they will issue takedowns.

It's not uncommon for forums to share links to resources, along with the password to decrypt them. And FF Send had a nice API for uploading material. It'd be an afternoon coding project to build a tool to re-upload material every 7 days, and update forum posts automatically so it could be available long term, beyond the max expiration time for anonymous uploads.

Consider implementing a 'guest upload' feature with stricter expiration policies and file size limits. This could maintain security while allowing for more flexible use cases, especially in client-facing scenarios where bidirectional file sharing is necessary.

Also supports Backblaze B2 per the docs.

Any recommendations for s3/b2 - anyone can upload (or with password) and only the admin can download?

Goal: allow customers to upload large files.

To go full aws on this:

- lambda vending s3 pre signed urls with put only permissions

- a static page with 20 lines of js that requests one of those urls and does the put

I’m not aware of any existing solutions, but your problem seems simple enough that you could roll a solution yourself

This is exactly what I use Firefox Send for in my org. It's not strictly "admin can download" but anyone with the password/link can download. The effect is the same.

I run https://www.wormhol.org

Ping me if you want your own instance.

It uploads to S3. I could make it such that only you/admin can download. Right now everyone with the link can.

Supports up to 5GB (S3's limit without doing multipart uploads).

Would it be better than seafile and it's share link functionality (it can be expired after x days as well)

Can we have this but something server less? Like using cloudflare workers and R2 (I know R2 is S3 compatible)

If this is something you’re interested in it can be reimplemented on CloudFlare workers super easily using the awssdk for s3 (R2) and with D1 as the DB.

Yes, but would be great if someone made it and is open source. Would be cool little side project, no doubt.

The source code is there - you could try to add the functionality to it :-)

I’m down, I think this is an awesome idea.

xkcd949.com is serverless (azure only tho, github.com/gfody/webrelay)

Whoops, http only

You could use Tailscale send

I need something like this but allows users to upload and send files. I don't want to make everyone admin.

The staying power of “Firefox Send” as a brand is baffling to me. It never did anything that wasn’t already available by multiple other services, didn’t do it better, and it was embarrassingly obvious from day one it was another one of those projects Mozilla would abandon in no time.

Just goes to show how powerful (and mismanaged) “Firefox” is a brand.

AWS S3 scares the shit out of me.

The company I worked for misconfiguration one of the buckets and allowed uploads. A couple of months later there was a bill for $15k. Since apparently some spammers were using our service. Which is OK for a company but I would not want to use it as a private individual.

Notwithstanding the fact that this was a user misconfiguration, S3 allows you to configure public access blocks to prevent this sort of thing.

These days, you have to remove the public access block AND explicitly write a bucket policy (or set up deprecated ACLs) to allow public access.

I have never had to use them directly but the use-now-pay-later model feels scary to me for the same reason. Maybe they allow setting the upper cap to the monthly bill (crossing which they don't serve you until you intervene) but I have never heard of it. On the other hand there are many stories extremely ballooned bills for some unforeseen reasons.

They have "AWS Budgets" for alerting you if you go over an amount but no automatic stops.

Not using the budget reporting feature is the bigger issue here IMO and just highlights that the organization was poorly managed.

Wow you can figure all of that out from a single sentence?

Yes, because not only was the projected cost not monitored, neither were changes to bucket security. They have entire suites of tools to monitor all of this stuff that is easily accessible.

This was back in 2006/2007 and the very first foray of that company into using cloud computing. Those tools you mentioned largely did not exist. And the UI's where a lot more confusing and less clear than they are now.

Another question: does any mistake in configuration signal a mismanaged company to you?

When you said "S3 scares the shit out of me", to me that implied that you still to this day didn't know about those features.

And no, mistakes do not necessarily signal a mismanaged company to me, but not knowing what you will be charged from one day to the next certainly smells like a bad policy to me.
