Firefox 74 is an excellent browser, and continues the Quantum era that. Mozilla went as far as saying that the new version has twice the speed of the older version. If you installed Firefox 57 Quantum and can't find some of your add-ons, they were most likely deactivated and now listed under the legacy extensions screen. Chrome is also shrinking its memory footprint in background tabs on macOS. Firefox's new CSS engine runs quickly, in parallel across multiple CPU cores, instead of running in one slower sequence on a single core.

Microsoft's Edge browser is the clear winner when it comes to tab freezing / sleeping functionality. A click on a tab reloads its content on demand. This improved utilization of your computer's hardware makes Firefox Quantum dramatically faster. Tabs and tab stacks remain on the tab bar but the content is unloaded.

Mozilla explains:įirefox has historically run mostly on just one CPU core, but Firefox Quantum takes advantage of multiple CPU cores in today's desktop and mobile devices much more effectively. Firefox Quantum is the culmination of Firefox's work on what it calls "Project Quantum," its effort to "create a next-generation engine for modern computers." Simply put, Mozilla says Firefox Quantum should instantly feel much faster thanks to work it has done to better take better advantage of your PC's multiple CPU cores.
