If you want to test PWA features, you need to trust the CA of the certificate for your local deployment. For your convenience, you can download the crt file from `http://<Your FQDN>:8080/ca.crt`. Install that certificate to the trust store of your operating system.
- On Windows, make sure to install it to the `Trusted Root Certification Authorities` store.
- On MacOS, double click the installed CA certificate in `Keychain Access`, expand `Trust`, and select `Always Trust` for SSL.
- On macOS, double-click the installed CA certificate in `Keychain Access`, expand `Trust`, and select `Always Trust` for SSL.
- 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.
- 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).
