I really love Firefox and think it to be one of the best browsers but just there is one problem with it. It really uses a lot of my battery and ram of my Macbook air M1. The amount of battery usage is significantly higher compared to other browsers (Even about 10 times more!), It is my request to Mozilla to fix this problem. Firefox is really awesome but it uses a lot of resources.

Check this:

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
