IPv4 sites errors when IPv4+IPv6 connected

Hello.

I've a problem while connecting to some sites - for example I can get "Server not found" when accessing "google.com". And no problems with "ipv6.google.com". My connection is mixed with IPv4+IPv6 (named Dual Stack PPPoE). Did the tests with https://test-ipv6.com/index.html.en_US and get warning: "Your browser has real working IPv6 address - but is avoiding using it. We're concerned about this." Checked chromium based browsers - no such warning and sites working with IPv6 and IPv4. Using latest Firefox 66b4. I think it need to be fixed.

Best regards.

I have no issues clicking on ipv6 google. Are you using default firefox settings?

Hi, WestEnd.

I have a problems (sometimes) when connecting to IPv4 sites(google.com for example), not IPv6. Anyway when connected to Internet over both technologies. And this test proves some problems with Firefox. At least on my configuration. I'm using default settings and configuration.
