Firefox Quantum

Who's tried this new Firefox Quantum (v57.0)?

Not liking the intial rollout because it made me have to either wait for new updates to my extensions or just do without. It does seem a bit faster though

On my desk top I have XP so I am blessed marooned in time with old Firefox.
On my net book, though, I got this Quantum automatically.
I have impression that the screen got smaller.
When I tried to "take a tour" and see new features, my net book got afraid and I had to restart it due "not responding" blockade.
The speed is questionable.
