> Latest version does multi-processing, e10s is finally here (though it might still get disabled by usage of certain add-ons, I remember I had to force it to stay enabled).

Are multi-processing and e10s separate things?

How do you forcefully enable it? 5/7 of my addins are listed as Legacy so I am still in single process mode, I am dying to try multi-process!

EDIT: See here: https://www.ghacks.net/2016/07/22/multi-process-firefox/

EDIT 2: Doesn't seem to work, for me anyways. It appears to be enabled in about:config but I only see one process running in task manager.

EDIT 3: I lied, it does work, 8 processes running now.

ALSO: Does anyone know if tree-style tabs will be made compatible, or if there is something comparable that is?
