Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

What OS? If windows, home or pro? If windows, are you running any security software besides MS Defender?
