Firefox displays a “Potential Security Risk” warning

Try reinstalling the certificate: In AdGuard, go to Settings → Network → HTTPS filtering and click Reinstall Certificate.
If that doesn’t help, follow these steps to add the certificate to Firefox manually (menu names may vary in other Firefox-based browsers):
Go to http://local.adguard.org/cert and click Download. The browser should start downloading the cert.cer file. You can also open the download page by clicking the link via the AdGuard app at Settings → Network → HTTPS filtering.
Open your browser, then open Settings.
Go to the Privacy & Security tab.
Scroll down to Certificates and click View Certificates.
Select Authorities.
Click Import...
Browse the downloaded cert.cer file and click Open.
Select Trust this CA to identify websites and click OK, then restart Firefox.
