If you don\’t want to drain your Windows 11 laptop\’s battery while out and about, Firefox can show you how much power specific websites use up. Here\’s how it works:
– In Firefox, go to the website you want to measure and click the three dots top right.
– Select \’Tools\’, then \’Web Developer Tools\’, and open the \’Performance\’ tab.
– Click \’Start recording\’ and hover your mouse over the power graphs to see how many watts of power the website is using.
