I know it's in vogue to pick on enterprise hardware marketed to "Secure your OT Environment" but actually written in crayon in a language made of all sharp edges like C or PHP, with some modules in Cobol for spice. This is the "Critical Infrastructure" risk du jour, on a thousand podcasts and panels, with *Volt Typhoon* in the canary seat, where once only the "sophisticated threat" Mirai had root permissions. As embarrassing as having random Iranian teenagers learn how to do systems administration on random water plants in New Jersey is, it's *more* humiliating to have systemic vulnerabilities right in front of you, have a huge amount of government brain matter devoted to solving them, and yet not make the obvious choice to turn off features that are bleeding us out. And when you talk about market failure in Security you can't help but talk about Web Browsers, both mobile and desktop. Web Browsing technology is in everything - and includes a host of technologies too complicated to go into, but one of the most interesting has been Just in Time compiling, which got very popular as an exploitation technique (let's say) in 2010 <http://www.semantiscope.com/research/BHDC2010/BHDC-2010-Slides-v2.pdf> but since then - for over a decade! - has been a bubbling septic font of constant systemic, untreated risk. Proponents of having a JIT in your Javascript compiler say "Without this kind of performance, you wouldn't be able to have GMail or Expedia!" Which is not true on today's hardware (Turn on Edge Strict Security mode today and you won't even notice it), and almost certainly not true on much older hardware. The issue with JITs is visible to any hacker who has looked at the code - whenever you have concepts like "Negative Zero <https://googleprojectzero.blogspot.com/2020/09/jitsploitation-one.html>" that have to be gotten perfectly every time or else the attacker gets full control of your computer, you are in an indefensible space. I would, in a perfect world, like us to be able to get ahead of systemic problems. We have a rallying cry and a lot of signatories on a pledge, but we need to turn it into clicky clicking on the configuration options that turn these things off on a USG and Enterprise level, the same way we banned Russian antivirus from having Ring0 in our enterprises, or suspiciously cheap subsidized Chinese telecom boxes from serving all the phone companies across the midwest. The issue with web browsers is not limited to JITs. A Secure By Design approach to web browsing would mean that most sites would not have access to large parts of the web browsing specification. We don't need to be tracked by every website. They don't all need access to Geolocation or Video or Web Assembly or any number of other parts of the things our web browsers give them, largely in order to allow the mass production of targeted advertising. If we've learned anything in the last decade, it is that the key phrase in Targeted Advertising is "Targeted", and malware authors have known this for as long as the ecosystem existed. The reason your browser is insecure by default is to support a parasitic advertising ecology, enhancing shareholder value, but leaving our society defenceless against anyone schooled enough in the dark arts. Google's current solution to vulnerabilities in the browser is Yet Another Sandbox. These work for a while until they don't - over time, digital sandboxes get dirty and filled with secrets just like the one in your backyard gets filled with presents from the local feral cat community. I know Project Zero's Samuel Groß is better at browser hacking than I am, and he personally designed the sandbox, but I look out across the landscape of the Chinese hacking community and see only hungry vorpal blades and I do not think it is a winning strategy. -dave References: 1.

As you note, the list is much longer than JIT - web fonts, WebGL, and so on. But I was there, and many of these decisions weren't about not grasping the risk, or prioritizing performance for the sake of it. Rather, they came from a place of terror: look at mobile applications cannibalizing the browser market share! If we don't give people the ability to build applications with as much flexibility as they have natively, the web will start shrinking, and we'll trade an open platform for a universe of walled gardens tightly controlled by companies such as Facebook. And you know, it's hard to offer a good rebuke to that. "Sure, the web might die, but it will die secure". In practice, yeah, some of this didn't matter. Web fonts were essential. WebGL enabled some niche applications, but it didn't revolutionize the platform. Stuff like JS JIT or WebAssembly probably weren't worth the price. But you only know this in retrospect. The fundamental problem with browsers is that the current way we think about them is kind of nuts - i.e., we design them as operating systems that can safely run untrusted code. But if you started with the paradigm that you don't want to expose anything risky or unproven to the world, you'd have ended up with a fairly niche document reader - plus a lot more native apps and monstrosities such as Java in the browser or Macromedia Flash.

It's not even about ad blockers: far too many extensions request overly broad permissions and then either do sneaky things (e.g., "monetizing" users by stealing browsing histories) or put users at risk. It doesn't help that if you pop a developer's account, you can essentially deploy a backdoored extension to all users *instantly*. But, there are many ways to improve this, and Google has chosen an approach that is inherently controversial given that they're an ad company and that their other divisions are openly waging a war on ad blocking right now. /mz

Does anyone have depth on this issue they can actually share? > Speaking about (but not for - this is just how I interpreted it) Firefox - mostly sausage making and org pains. Fennec (the old mobile architecture) supported extensions, although I don't remember to what extent/how well. In 2016 it got WebExtension support - before that it was supporting extensions in the old style of "Just let them do whatever they want in the browser, I'm sure it will be fine.[0]" And in late 2017 we removed access to those capabilities. Somewhere around 2019 we switched from the old browser architecture (Fennec) to the new one (Fenix) - and 2019 was when we launched, so we started the development quite some time earlier and kept Fennec on life support during it. Fenix - while not a total rewrite of the rendering or js engine - was a rewrite of everything else, including the UI, accounts, sync, telemetry, session storage, push, reader view, downloads, etc etc. [1] Getting a consistent and reliable handle on the Android OS process management also took time[2] - running extensions in the parent meant the parent got reaped a lot; they needed to be moved to a separate process, and then we needed to handle how to behave when _that_ process got reaped but others did not. Fenix supported a curated list of extensions (including Ghostery, AdGuard, and uBlock Origin) for a while, but in the past 6 months finally hit the milestone where it opened up so anyone can publish, and anyone can install, an extension on Android without jumping through hoops. Add into all of this mix a couple rounds of layoffs including the big one in 2020, which disrupted a lot of things. (And, you know, the pandemic.) I don't know/remember if anyone directly working on Fenix was let go, although I would wager yes, but I do know many *mobile* engineers in non-Firefox products were let go and I have to assume the knowledge drain, upheaval, and hurt when your colleagues are let go led to departures and general delays in what people originally hoped to accomplish. Anyway, I don't know if you wanted more technical nitty-gritty on it, but from my perspective, that's what I can offer. I don't think there was any specific de-prioritization of extensions from a philosophical standpoint (we all know that extensions are what made Firefox what it is), just juggling lots of work that resulted in a slower rollout than we hoped. -tom ref: https://blog.mozilla.org/addons/page/1/?s=android [0] Narrator: It was not fine. [1] Unsurprisingly we've been playing whack-a-mole with re-implementations of the annoying 'yes it's a bug but no one exploits address-bar-impersonation so =/' class of bugs. [2] 'Takes time' is both engineering time and wall-time as you write code, deploy it, run an experiment, and wait for results.
