Firefox 54 Released: Multi-process, Optimized Memory Footprint
The Mozilla Foundation has recently launched the latest version of their Firefox web browser. The foxiest web browser around, which lets you access all of those amazing websites (like TPU) now features increased support for multitasking through its multi-process technology. A result of the Electrolysis effort from Mozilla's part, which has spawned more than eight years of work, Firefox 54 applies the Goldilocks principle to browser design, straddling an approach between increased performance and acceptable memory usage.
As such, Firefox won't be like Chrome, where each process is responsible for a single tab and its content handling (and can therefore increase memory usage immensely, which has justified Chrome's fame as a memory hog), but will instead opt for a more streamlined approach. Open 10 different tabs with 10 sites in Chrome, and you'll have 10 different processes. Each of those processes has its own memory - with their own instance of the browser's engine. Au contraire, Firefox now creates up to 4 separate processes for web page content. This means that the first 4 tabs each use those 4 processes, and additional tabs run using threads within those processes, optimizing, as per Firefox, memory usage and performance.
