When an app is in full screen mode the operating system can determine to discontinue some background tasks.
You can put two or more apps to full screen view and then use three fingers to swipe left/right on your trackpad to switch between those full-screen apps.
See "System Preferences", "Trackpad", "More Gestures", "Swipe between full-screen apps".

QupZilla
Firefox
(When comparing web browsers, remember to start them approximately at the same time after starting your computer, use them for the same period of time and use them on the same web pages for more reliable "Avg Energy Impact" on "Activity Monitor".)
