How is it not? I remember being bombarded with news along the lines of 'New Firefox is blazingly fast!'. Which one is that? How do I get a version that has the new engine?
The part that shipped was Electrolysis which splits the formerly giant-single-processed Firefox into a set of 1-9 processes which work as task pools for tabs. Locking one tab hard will lock only that tab, and any others sharing that Electrolysis worker I believe.
The new upcoming part is Servo, the rendering engine written in Rust.
