Thanks for testing e10s! There&#x27;s a simpler a better way to test it though, which is just setting
`browser.tabs.remote.autostart` to true.<p>These prefs that you mentioned won&#x27;t stick (they will be reset after startup) and are just used for some internal state.<p>I&#x27;ll make sure the info on that wiki page is up to date for people who want to test it.<p>Note: Multiprocess is not available in the Release channel yet. Please use our Developer&#x2F;Test channels if you want to use it.<p>Also, if you have add-ons, multiprocess is by default blocked from running on Beta (but allowed on Nightly&#x2F;Aurora). If you&#x27;re on Beta and want to use it together with add-ons, look at that wiki page to see how to work around that.  Or just use Aurora :)
