https://addons.mozilla.org/en-US/firefox/addon/memory-fox-next/ In the firefox trunk version, clicking 'Activate Memory Fox Next - Browser Only', instantly decreases the memory of firefox.exe process. In nightly with e10s enabled, clicking that option doesn't decrease memory of neither firefox.exe nor plugin-container.exe.
WFM in 47.0a1 (2016-02-05), the works fine.
With Firefox 57 only WebExtensions are permitted and are, by default, e10s compatible.
