Hello, I'd like to ask if there's an addon available or a hidden feature in Firefox which allows it to enable trying to use other DNS servers if a connection failed to a server. Lets do an example, would be the easiest way of explaining: 1. I want to connect to Google.com 2. Firefox / Windows asks the DNS server for the IP 3. Firefox tries to connect to Google but fails (Website took to long to answer for example) 4. Firefox will try another DNS server you have entered in your IPv4 DNS Page Or does Firefox already do that? Because sometimes it fails to connect to a server while using a special DNS server. If I change the settings to another DNS Server it works. Thank you
