Re-enable multi-E10S when not debugging ServiceWorkers?
When I started experimenting with ServiceWorkers in Firefox Developer Edition recently, I consented to disabling multi-E10S, but now it seems to be stuck on disabled even when I don't have about:debugging open and debugging a ServiceWorker. I've tried changing a few of the prefs in about:config as suggested for accessibility stuff that may disable it, but no luck. I'd love to get my performance back. :|

Have you tried setting the browser.tabs.remote.autostart preference to true? There may also be some sub-preferences like browser.tabs.remote.autostart.2 that should also be set to true.
NOTE: You will need to restart Firefox in order for the changes to take effect.
Only browser.tabs.remote. is used in current Firefox releases. If there are still other bold autostart prefs then you can reset them via the right-click context menu.
Maybe check this pref:
- dom.ipc.processCount
- Options/Preferences -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings" - https://support.mozilla.org/en-US/kb/performance-settings
