This feature will probably upset a lot of users, but it is a security feature that is essential in today's digital threat environment. Although this feature was introduced on an earlier version of Firefox, it had an option that let users disable it. The mandatory add-on signing process will prevent users from installing add-ons unless it has been approved by the testers at Mozilla. This protection was put in place because media playback code is an attack vector used by hackers on desktop and mobile platforms to exploit vulnerabilities.īeing able to install any add-on on to Firefox has been the norm until now, but that is no longer the case.

The media parser written in Rust is going to make it much harder to crack. Rust is a memory-safe programming language designed to provide the performance capability of C++ but without the security flaws. This feature will be released in three parts, beginning with Firefox 48 and ending with Firefox 50, when Electrolysis will be enabled for all users, including those with add-ons.

Initially only 1 percent of users without any add-ons in their browser will get it, followed by 50 and 100 percent of the same user group. Support for e10s is not going to be a wide release.

What this means for the user is, if one tab crashes or freezes, the browser or other tabs won't be affected with the same problem. Electrolysis, e10s, or multi-process support is able to separate the process on the browser.
