Analyze the Power Usage of Websites on Firefox
A shortcoming of this new feature is that it is only available for Windows 11 and Apple M1 devices. The information about Power Usage can come in very handy for several users who have battery-dependent devices. By analyzing what websites are using power to what degree, a user can plan their usage accordingly with a given battery life. As mentioned, to get your hands on this feature you’re required to have Firefox 104 stable running on your Windows 11 PC. Let us see what are the steps that you need to follow:

- Click on the Performance tab and from the settings drop-down, select ‘Power’

- Once you’re done using and want to evaluate the data and power used, stop the recording by clicking on ‘Capture recording’. Doing so would automatically launch the Firefox Profiler website
On the Firefox Profiler website, you will have to scroll down to get to the sections that provide you with information on how many CPU packages and CPU cores go with a website’s usage.
