Firefox 96 cannot connect to any website, even in local network or to send crash reports. One of Firefox processes constantly loads 1 cpu core. On trying to close Firefox, crash happens.

Error persists even in Troubleshooting mode, with new profile and reinstalled Firefox. With older Firefox 88 I don't have this problem.

Environment: Windows 10, Firefox 96.0
