Firefox 48 is expected to be released as a stable version in August 2016 and will come with a notable change, the “Electrolysis”.
This feature, which will be enabled by default, is also known as mode multi-process or simply E10S.
E10S or Electrolysis it works almost like the technique called chemistry by electrolysis and which, for example, can divide the water into hydrogen and oxygen. So for Firefox, it will be used to separate a UI process and a content process. Breaking UI from content means that when a web page devours a large percentage of your CPU, you will be able to actively and functionally record your tabs, buttons, and menus.
With the arrival of Firefox 48, E10S will be enabled for the 1% of users, those who do not use much or not at all add-ons. If this experiment resolves the theme of the computer's excessive consumption of processing power, then the percentage of users for which E10S will be activated may increase. If it causes problems, then the Mozilla developers will probably suppress it.
The drawings, however, are that with the arrival of Firefox 49, E10S will be enabled for all users who use Firefox without add-ons. According to Mozilla, 40% of all Firefox users never use add-ons.
Electrolysis will allow the Browser to make each content of each tab as a separate process, which will be independent from the main browser process. This should increase the security of the browser, the program will not "hang" as a reference and it will speed up on multi-core processors.
The disadvantage of this change is that E10S will be incompatible with many popular extensions including NoScript, Ghostery, Flash Video Downloader and Adblock Edge.
