The E10S indication is probably not supposed to be user visible. You can check it though:

Go to about:support page and in the first page, check the Multiprocess Windows row.

And for those that look at about:support and see it's disabled for some reason (an add-on you use doesn't play nice with it is the common thing), you should install an add-on called Add-on Compatibility Reporter, to tell you which one is causing you issues.
