+- Make sure to install it to the `Trusted Root Certification Authorities` store.
+
+##### macOS
+- Double-click the installed CA certificate in `Keychain Access`,
 - expand `Trust`, and select `Always Trust` for SSL.
+
+##### Firefox
 - Firefox uses its own trust store. To install the CA,
 - point Firefox at `http://<Your FQDN>:8080/ca.crt`.
 - When prompted, select `Trust this CA to identify websites` and click _OK_.

+##### Chrome
 - When using Chrome, you need to restart Chrome so it reloads the trust store (`chrome://restart`).
 - Additionally, after installing a new cert, you need to clear the Storage (DevTools → Application → Clear storage → Clear site data).
 
+##### Google Chrome
+- To skip the installation of the certificate, you can also open `chrome://flags/#unsafely-treat-insecure-origin-as-secure`
+- The feature `Insecure origins treated as secure` must be enabled and the list must include your PairDrop test instance. E.g.: `http://127.0.0.1:3000,https://127.0.0.1:8443`

 Please note that the certificates (CA and webserver cert) expire after a day.
 Also, whenever you restart the NGINX Docker container new certificates are created.
