Electrolysis isn't enabled by default It is enabled by default, you just may have a plugin installed that is blocking it. The plugin(s) could be multiprocess compatible but unmaintained and missing the multiprocess=true flag in its package.json. You can go to about:support to see if multiprocess is truly enabled. If not, go to about:addons and start disabling extensions until it does work.
