> Safari made third party tracking impossible by gradually fully segmenting everything - HTTP caches, LocalStorage, cookies, etc. - I haven't been following exact features between browsers too closely recently, but Firefox's Tracking Protection has been around for a while and improving for years; and of course, Firefox is where AdBlock/uBlock originated. What does Safari provide that Firefox does not? How does it affect web compat? > and Chrome made JIT exploitation and then Spectre attacks in JavaScript impossible by using process boundary separations and applying sandboxes to purpose built processes. This feature has been a long time coming in Firefox, and it's still not all the way there. But Firefox did just release an opt-in process isolation feature for Firefox, which applies stricter cross-origin controls for a variety of content, and in exchange gives web developers access to SharedArrayBuffer, the feature that needed to be disabled to mitigate Spectre attacks. So site isolation is progressing, and the first iteration of it has been released. > What awesome technical choices do you think Mozilla has made recently? The development of Rust. Servo, which acted as an experimental testbed for a parallel browser engine and has led to its CSS parser, WebRender, and a number of other components being used by Firefox. Asm.js as an alternative to NaCl, which led to the joint development of WASM.

I appreciate that site isolation is in progress in Firefox, but it came out in Chrome two years ago (three now?). You're telling me that the soon to be released IE7 will include a pop-up blocker, so I should switch back to IE from Firefox. > I haven't been following exact features between browsers too closely recently, but Firefox's Tracking Protection has been around for a while and improving for years; and of course, Firefox is where AdBlock/uBlock originated. What does Safari provide that Firefox does not? How does it affect web compat? Firefox, like uBlock and AdBlock is list based - it forbids known bad actors. Safari is changing web standards to make tracking impossible, regardless of whether or not you are a known actor, and doing it gradually and carefully enough enough where breakage is minor enough that users don't complain. And Safari has less market share than Firefox. Look at e.g. https://webkit.org/tracking-prevention-policy/ https://webkit.org/tracking-prevention-policy/ for the principles and the other posts on the blog for details about the implementation. It's an industry wide change that a non-advertising funded browser company needed to push, and it just needed a real leader to push it. And that person turned out to be John Wilander (https://twitter.com/johnwilander https://twitter.com/johnwilander). For whatever reason (I've given my thoughts above), I think Mozilla struggles to attract these sort of talented experienced mid-career people. Rust is pretty cool, but Servo is pretty immature, and it seems like Mozilla just fired all those people. I dunno. I don't see a bright future there.

  > Rust is pretty cool, but Servo is pretty immature, and it seems like Mozilla just fired all those people. I dunno. I don't see a bright future there. Well, yeah, that's the problem. Until now, I felt like despite its issues, Mozilla was mostly on the right track. There have been a few mistakes here and there, but it was fundamentally doing good work. However, cutting Servo, and it looks like maybe Cranelift as well (not sure about that, but Dan Gohmen aka sunfishcode, who seemed to be one of the lead contributors, has been laid off) is a huge blow. While Servo as a whole browser is pretty immature, a number of components of it were adopted by Firefox, such as its CSS parser, Webrender, its GPU accelerated parallel rendering engine, and more. You had asked about what Mozilla had done recently, and I listed a few things. But it looks like they are cutting a lot of that. They mentioned focusing on wasmtime and the Bytecode alliance, but I don't see how cutting one of their lead contributors helps out with that. And they seem to be slowly cutting the head count on Rust; it's less apparent because there are enough people not at Mozilla contributing, and some of the core contributors have been moved onto other projects which use Rust at Mozilla so while they're not contributing directly they are still somewhat involved; and some folks have left of their own accord. But now it looks like some of those other teams are being cut, like Servo and at least some of the wasmtime team, so I really hope that more companies can put some more investment directly in Rust, as well as the WASM ecosystem.
