Sometimes the free browser FireFox establishes a so-called "secure connection" with a site, meaning that FireFox encrypts the connection and also verifies the site’s certificate. These measures are necessary to protect the user from all kinds of fraudulent schemes, viruses, etc. However, such measures are sometimes unnecessary and simply prevent the user from visiting websites.
In that case, you can disable such checks. If, when visiting websites, you too often see the message "This connection is not trusted You asked Firefox to establish a secure connection with 'site', but we cannot guarantee that this connection is secure", you can turn off this warning.
To do this, go to the security settings of FireFox, where you will find the settings you need.

However, by disabling checks, you expose your computer to danger, so we advise you to do so only as a last resort. Even better, use "Exceptions" to allow access to the sites you visit and block all unsafe ones.
Good luck!
