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.
