At Firefox, we know that you’re looking for the fastest web browser out there. You need to load web pages quickly and work at top speed. To make sure the Firefox Quantum (‘57) is the fastest Firefox yet, we ran some tests*.

The tests compared Firefox Quantum (57)’s speed and memory against previous versions of Firefox, and of Chrome. They found that while results varied based on your computer and the apps you’re using, Firefox Quantum was approximately 2x faster than any previous version of Firefox.

In addition to speed testing, Firefox’s “just right” multi-process architecture results in Firefox Quantum consuming roughly 30% less RAM than Chrome.

To compare memory usage, the atsy project was used to load 30 pages, each in its own tab, with 10 seconds in between loads and 60 seconds of settle time at the end. Then memory usage was measured for the various processes that each browser spawns during that time.
