>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.
>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, mobile browsers outperformed their desktop counterparts. They’re faster to load pages, able to crunch through more intense web apps and generally just better browsers.
