Hi!

In about:support I've Multiprocess Windows : 0/1.

However I've set browser.tabs.remote.autostart to true.

I've also tried this on vanilla FF (no addons, downloaded tar.bz2).

OS is Debian 8.

hi, e10s is not yet supported in firefox 45 and is switched off (hardcoded) regardless of that preference. if you'd like to test e10s already, you'd have to use other prerelease builds.

A far as I am aware e10s is not supported yet on Releases. Have you seen anything official to say otherwise ? It is up and on by default in DE (nee Aurora) currently Fx 47.0a2 and has been for quite a while
