As someone with an app built on firebase, yes. As the author rightly points out, it's very easy to misconfigure, but basic security practices like these are highlighted in bright, bold warning text in the Firebase docs. Security rules are meant to be taken seriously, and it's your only line of defense.

Nobody reads docs dude. They copy and paste stack overflow answers, and now, copilot answers, which is going to be based on stack overflow ultimately anyway.

Just with less context and review.

>privacy concerns >while researching, i saw some data being sent over to the server, like this query everytime you visit a site: > firebase .collection("boosts") .where("creatorID", "==", "UvMIUnuxJ2h0E47fmZPpHLisHn12") .where("hostPattern", "==", "www.google.com"); > the hostPattern being the site you visit, this is against arc's privacy policy which clearly states arc does not know which sites you visit.

Maybe I am just stupid, but this *super* smells of arc being able to inject whatever they want in to literally any of your websites and this dude just figured out that he could also do that.

This does not seem like a browser capability I want.

Arc is a great product, it's the nicest web browser to use, you can tell these people are really good at their jobs in many respects (though apparently not security?!?). probably a lot of investors saw that too and are willing to fund a very strong team with the hope of eventual product-market fit.

It’s just another dumb social media trend, like tYpiNg LiKe tHiS. Hopefully it too will phase out. Search for “lowercase trend” and you’ll find reports of it going years back, there’s nothing worth being fascinated about. It has seeped into HN as well. Look closely and you’ll notice several commenters type like that.

I use it to indicate tone. Proper capitalization and punctuation reads with a formal, cold tone. lowercase without caps reads with a warmer, informal tone there’s a Tom Scott Language Files video documenting it: https://www.youtube.com/watch?v=fS4X1JfX6_Q

> lowercase without caps reads with a warmer, informal tone

No, it reads as "I'm uneducated and don't know how to write the English language properly". It's incredibly obnoxious for people to use as an affectation.

According to this article, Arc requires an account and sends Google's Firebase the hostname of every page you visit along with your user ID. Does this make Arc the least private web browser currently being used?

I think OperaGX wins that award

I'm also left wondering: How broken would Arc be, if Firebase was to go down?

> bold warning text in the Firebase docs. Unfortunately, we currently have an industry where highly paid "engineers" unironically believe that their job can be done by reading/watching random tutorials, googling for StackOverflow answers, and pasting code from gists. Attentively reading documentation or developing a mental model of how your tools work so that you know how they are built to be handled does not make it…

"don't trust the client / validate inputs" is software security 101

There are a lot of major security vulnerabilities in the world that were made understandably, and can be forgiven if they're handled responsibly and fixed. This is not one of them. In my opinion, this shows a kind of reputation-ruining incompetency that would convince me to never use Arc ever again.

The mandatory account just to try Arc was always a massive red flag to me - and led to me never trying it. Now I’m glad I didn’t!

No Linux version prevented me from trying it, didn't even get to the account wall, who knows if there's a pay wall. Perhaps the "moat" concept was misunderstood.

I guess it's relatively easy to test, add the Firebase domain to your host file and point it to 127.0.0.1 and try to use the browser.

Sometimes things like this handle connection failures better than "never-ending connection attempts", so you might want to try to add a throttle or something too for the traffic between the domain and the browser, might also trip it up.
