Expecting a big publicity drive from Mozilla soon, because if Firefox 57 ends up as snappy as Nightly is right now, it could win back some of the people who want to support Firefox but eventually moved to Chrome for performance reasons.

Then once WebRender lands, well, who knows? I assume Google are planning something in response - the continued dominance of Chrome is worth considerable $billions to them...

Yes nightly is really fast and I'm really enjoying using it. But the missing extensions (mostly LastPass in my case) is starting to grind, even though a large number of extensions are already ported.

I’m impressed by how stable it is! I know it’s a nightly that’s two stable versions “behind,” yet it’s been totally solid for me so far.

I’m surprised the built in containers left behind the extensions option to always a url open in a specific container. To me that’s the unique interesting bit — my banks can always be in my banking container, Facebook in a social, etc. By having the browser force the mapping I can make sure that I minimize cross-contamination, reducing attack surface area and increasing privacy.
