Details
I was trying to figure out why my Firefox was janking in the parent process today while scrolling Gmail, so I profiled. There are expensive calls to stuff in multiprocessShims.js from Mega. See this profile for example: <https://clptr.io/2gJnTvh> Looking at chrome://mega/content/e10s.js, the add-on is accessing content nodes from the parent process.

With Firefox 57 only WebExtensions are permitted and are, by default, e10s compatible.
