>In my testing, I found surprising differences. To test how much each browser taxes my system, I loaded the same 10 sites on each browser and watched them gorge on my MacBook’s RAM. Chrome, a notorious resource hog, took up the most memory, with Safari and Opera close behind. Firefox, though, required 30% less RAM than Chrome to run the same stuff.<p>>Among mobile browsers (which I tested on an iPhone XS and a Google Pixel 2 XL), the differences were smaller. Surprisingly, in every single case, <i>mobile browsers outperformed their desktop counterparts.</i> They’re faster to load pages, able to crunch through more intense web apps and generally just better browsers.
