Updated info about enabling e10s
In Mozilla documentation "Electrolysis" is often shorted as "e10s".
==Enabling and Disabling Electrolysison Nightly/Aurora==
If you're on Nightly or Aurora, e10s is already enabled by default! A user facing checkbox is available in developer builds (Nightly, Aurora) for controlling Electrolysis functionality. Open Preferences and check the "Enable multi-process" checkbox and then restart your browser:
[[File:E10s-toggle-in-preferences.png|324x150px|frameless|Nightly > Preferences > General > Enable multi-process]]
For release builds (Beta, Release, ESR) enabling Electrolysis is controlled through an internal preference.
== Enabling and Disabling Electrolysis on Beta ==
If you're on beta, you might be using / have already used e10s for some periods of time as we're running experiments to evaluate its stabililty.
However, if you want to permanently opt-in, you can do so with a simple pref change. Just go to ''about:config'' and toggle '''browser.tabs.remote.autostart''' to true. On your next restart, e10s should be active. To verify that it is active, go to ''about:support'' and look for a number higher than 0 in "Multiprocess Windows".
== Enabling and Disabling Electrolysis on Release ==
Multiprocess is not yet available on the release channel. Stay tuned! If you really want to test it we suggest you to use Beta and help us test it!
== Force-enabling e10s ==
If you've tried to enable e10s, but you see information in about:support saying that it is Disabled by some reason, you can create and set to true a pref called '''browser.tabs.remote.force-enable'''. That is not encouraged though, so use it at your own risk, and only if you know what you're doing.
== What to Expect ==
