Problems in Windows 11

I have many problems with Firefox for Windows 11. Unfortunately, it occupies a very high amount of cpu above 88% and memory above 700 MB with two or three open screens and has a very high battery consumption, consuming more than 41% of 100% battery in less than an hour. Also, I used it a lot in Windows 10 and it was not like this at all, and its automatic update was perfect in Windows 10, but it does not work in Windows 11. Thank you for your attention and correcting software updates in the very near future

Hi Erfan, could you take a look at Firefox's built-in Task Manager and see which part of the browser is hogging your CPU? To call that up, you can press Shift+Esc, or type/paste about:processes in the address bar and press Enter to load the page. This could help identify a problem with specific content or a particular add-on.

If the built-in Task Manager is missing processes that you can see in the Windows Task Manager, there might be a separate instance of Firefox running, which we'll need to help you investigate in more detail.
