February 15, 2023 by Mike Knight

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.
