Firefox 54 enables multiprocessing to gain performance and stability

Mozilla has unveiled Firefox 54, its web browser’s newest version. Its main feature is that multiprocessing is enabled by default for all versions and users while aiming to gain performance and stability by taking better advantage of the PC’s hardware.

Mozilla has been pondering about using multiprocessing in Firefox since 2009, implementing it in Project Electrolysis (e10s) in 2015 and enabling it in Firefox 48 last year so a small number of users could test it.

Google pioneered this technique by enabling it in Chromium, which is the basis for Chrome and other browsers such as Opera or Vivaldi. As the technique’s name suggests, Google creates a process for each tab and extension that loads web content besides the general process that runs the interface. The great performance and stability both brands offer is due to this, even at the cost of a large resource consumption, mainly of RAM memory.
