I maintain a long-term Rust + Node.js project, and the Node side is the painful one.

Node makes backwards-incompatible changes, and doesn’t have anything like the editions to keep old packages working. I can end up with some dependencies working only up to Node vX, and some other deps needing at least Node v(X+1).

Yes, it’s Blink without the bits that Google doesn’t share (I wanted to be precise that nobody can compile actual Chrome from public sources, they can build Chromium which is almost but not quite the same)

Vivaldi uses the same engine as Chromium, and the company has been founded by ex Opera developers.

Plus you can make certain sites always automatically open in their designated container, even if you followed a link. You can keep sites know for spying away from your logged in identity. You can have your banking and other important sites in another container for extra defense in depth.
