The 1.0 and 1.1 versions of TLS are considered insecure. Modern browsers therefore no longer support them directly. In most cases, this is not a problem, unless you stumble across an older website that still uses the old method and the provider no longer cares about it.<\/p>\n<p>If you still want to have access to the page, you can still enable this in the settings. To do this, we enter &#8220;about:config&#8221; in the address bar.<\/p>\n<p>Now we enter &#8220;security.tls.version.min&#8221; into the search field. Change the value to 1 or 2 and the access will work.
