Thanks very much for this informative response--you even provided the date / revision number of the change! So, I'm now reading up on electrolysis--hadn't seen / heard anything about it before now. The first thing I started to read (still more tabs open to skim / read) indicates that the first iterations of e10s just put all the web content in one process, but maybe future ones (maybe even by now), maybe each tab will be a separate process, which is the point at which, at least usually, one crashed tab will not bring down the entire browser. > I noticed the new process for the first time within the last > month but wasn't sure how long it had been there ...

I guess I haven't looked at top since something like August 21, thus hadn't noticed the change--not looking at top in that time is a good thing, because it implies I had no problems that made me look at top ;-) > I believe the ESR release channel gained > the multiprocess feature with the change from release 45.x.y to release > 52.x.y (Debian tracks the ESR channel), and my Wheezy systems received > FF52.2.0 on 21st.August. Thanks again! OH, and for pointing out that "Web Content" is a process--I should have recognized that, but did not till I read your reply. ;-) (I guess, at first, I thought it was just some magical thing that magically separated Firefox's memory use into two parts, one that just reflected the content (well, it is that, but by virture of being a separate process).

That must have been part of a (recent) "security" update ;-) AFAIK the 'Web Content' process was introduced by Mozilla when Firefox switched to a multi-process model for the browser binary - you may have seen people moaning about it: Mozilla calls it 'electrolysis/e10s' and it delivers such things as "only one tab will crash, rather than the whole browser". I noticed the new process for the first time within the last month but wasn't sure how long it had been there ... I was trying to find out where all my RAM was going, and the sight of it made my blood run cold till I found out what it was. I believe the ESR release channel gained the multiprocess feature with the change from release 45.x.y to release 52.x.y (Debian tracks the ESR channel), and my Wheezy systems received FF52.2.0 on 21st.August.

David, Thanks very much for your reply! Son of a gun, this morning I looked at top and now there is a task named "Web Content". That must have been part of a (recent) "security" update ;-)

That is what ps calls it in jessie, but I used top's value and terminology. Another name to check out might be xul-runner which is where plugin-container used to live. Cheers, David.

I don't see that in top on Wheezy., but I'd like to get that number.
