Firefox still doesn't use process separation between page rendering and the browser chrome. The thing that renders the pages on Chrome is a subprocess per tab (at considerable memory cost) which is also running in a sandbox.

In Firefox all tabs run in the same process and thus inherently can't be sandboxed (because it needs to write to the disk cache and save files the user downloads)

Dev Edition has process separation and content process sandboxing.

Now we only have to wait 5 years until they found all the obvious sandbox escape bugs.

Thanks for that. I knew about the sandbox but wasn't sure if there was something else (newer) that I missed.
