hi, unfortunately this will be caused by adguard - either disable/uninstall it and use a built-in adblocking addon in firefox like https://addons.mozilla.org/firefox/addon/ublock-origin/ or follow adguard's instructions how to set it up so that its certificate is trusted by firefox: https://kb.adguard.com/en/windows/solving-problems/connection-not-trusted
