Seat of the pants it actually seemed quicker on new tabs. Memory I haven't checked but good news nonetheless.
Many thanks Mozilla devs.

how can they relaunch with the new binary without relaunching the binary? what's behind this Linux magic?
-
It doesn't launch the new binary at all. When the current process wants to create a new process, instead of doing fork+exec (which launches the new binary and wreaks havoc because versions now don't match), it simply tells the ForkServer (a different process running the old binary) to fork (split) itself.
Chromium also does this; they call their equivalent to ForkServer the zygote process and this article explains it really well.

Thank you, I feel smarter (no)!

Will this stop the constant crashing I've been having the last several versions?
