Firefox does not connect to any website and crashes on exit
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

I appreciate that you may have done this already, but please can you restart Firefox which should resolve this issue.
