Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. If you want to leave feedback for developers, you can go to the Firefox Help menu and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
