Can't connect to addons.mozilla.org
I can't connect to some safe websites, which i used before the 66th version of the browser. For example, i can't connect to Firefox's services such as addons.mozilla.org because of issue "SEC_ERROR_UNKNOWN_ISSUER"
The whole message (on Russian): "addons.mozilla.org имеет политику безопасности называемую Форсированное защищённое соединение HTTP (HSTS), что означает, что Firefox может подключиться к нему только через защищённое соединение. Вы не можете добавить исключение, чтобы посетить этот сайт.
Скорее всего, эта проблема связана с самим веб-сайтом, и вы ничего не сможете с этим сделать.
Если вы находитесь в корпоративной сети или используете антивирусную программу, вы можете связаться со службой поддержки для получения помощи. Вы также можете сообщить администратору веб-сайта об этой проблеме. Кто-то может пытаться подменить настоящий сайт и вам лучше не продолжать. Веб-сайты подтверждают свою подлинность с помощью сертификатов. Firefox не доверяет addons.mozilla.org, потому что издатель его сертификата неизвестен, сертификат является самоподписанным, или сервер не отправляет корректные промежуточные сертификаты. Код ошибки: SEC_ERROR_UNKNOWN_ISSUER"

It is possible that you have a corrupted "DigiCert SHA2 Extended Validation Server CA" certificate.
If you can locate this "DigiCert SHA2 Extended Validation Server CA" certificate in the Certificate Manager under the Authorities tab then try to remove this certificate. It should have a "Software Security Device" designation.
Otherwise try to rename the cert9.db (cert9.db.old) file and remove the previously used cert8.db file in the Firefox profile folder with Firefox closed to remove intermediate certificates and exceptions that Firefox has stored. Note that current Firefox releases use a cert9.db SQLite database file.
If that has helped to solve the problem then you can remove the renamed cert9.db.old file. Otherwise you can undo the rename and restore cert9.db.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:preferences page.
