Make a plan on how to deploy e10s in Tor Browser
Our current goal is to make Tor Browser based on ESR 52 ready for content sandboxing (e10s). While the work is done in different bugs we need to create a plan on how we want to deploy it. For that we need to investigate first how Mozilla is shipping it in Firefox 52 ESR. E.g. there is a system extension
e10srollout and there is an e10s allow list and probably some other means that are regulating which users are getting which experience (i.e. having e10s and non-e10s) activated (Things like https://bugzilla.mozilla.org/show_bug.cgi?id=1329695 make me quite cautious).
Once we know how this is going to work (mike conley had an idea in: https://groups.google.com/forum/#!topic/mozilla.dev.platform/TWE4VEbJOmM not sure if that's the final word or where we can find out more information) we can think about how we want to have it work in Tor Browser to have a stable yet more secure browsing experience.
