Mozilla is working on Firefox's multi-process architecture that it calls e10s and interested users can enable it in some versions of Firefox already.
If you have tried it already you may have noticed that some sites or add-ons that you are using are not working properly when e10s is enabled in the browser.
If you are interested in the progress that is being made in regards to add-ons, then you may want to head over to the Are we e10s yet website which lists popular add-ons for Firefox and their compatibility state.
There you find listed HTTPS Everywhere for example which is listed as not compatible right now. Each add-on that is not working at all or only partially has a bug assigned to it that is used to keep track of its compatibility progress.
The Electronic Frontier Foundation has just released a new development build of HTTPS Everywhere for Firefox, HTTPS Everywhere 5.0 Development 1 which is e10s compatible.
Firefox users who use e10s and HTTPS Everywhere can use this build to use both together.
Note though that you are running a development version of Firefox if you use e10s already and a development build of an add-on. There is no guarantee yet that everything will work fine at this point.
HTTPS Everywhere is not the only extension that is listed as not compatible right now. If you go through the list you find a massive amount of add-ons that don't work yet including the following ones:
This is just a small selection of add-ons that don't work at all or only partially if e10s is enabled in Firefox. Mozilla seems to have contacted authors of said add-ons and while that may work for some, it won't work at all for abandoned add-ons for obvious reasons.
There is still -- some -- time left and it is very likely that many of the extensions listed as partially compatible or incompatible will become compatible before e10s lands in Firefox Stable.
On a personal note, I had to disable e10s in Firefox Nightly recently as I ran into a series of issues that made the browser unusable for me.
Now You: Have you tried the multi-process feature yet? If so, what is your take on it?
