> So I think this is not really a leap for the web. Just FireFox catching up a bit. To be clear, Project Quantum is the next phase of architecture, post-Electrolysis. We're also simultaneously working on multiple content processes (which is how Chrome often avoids inter-window jank), but not under the Quantum umbrella. We think we can do better though, which is where Quantum comes in. The Quantum DOM project is designed to solve exactly the problem you're describing, while using fewer resources and scaling to more tabs. Stay tuned!
