The "DNS server failure" error in Firefox usually occurs when the web browser is unable to establish a connection to the DNS server to resolve domain names. Here are some possible solutions: Check your internet connection: Make sure your internet connection is working correctly by trying to access other websites. If you're not able to access any websites, then the problem is with your internet connection. Clear the DNS cache: Sometimes, the DNS cache can become corrupted, leading to this error. To clear the DNS cache, open the command prompt and type "ipconfig /flushdns". This will flush the DNS cache. Try a different DNS server: You can try using a different DNS server, such as Google DNS (8.8.8.8) or OpenDNS (208.67.222.222). To change your DNS server, go to your network settings and change the DNS server address. Disable DNS prefetching: DNS prefetching is a feature in Firefox that can sometimes cause the "DNS server failure" error. To disable DNS prefetching, open Firefox and go to "about:config". Search for "network.dns.disablePrefetch" and set it to "true". Restart your modem/router: Sometimes, restarting your modem or router can fix the problem. If none of the above solutions work, you may need to contact your internet service provider (ISP) or IT department for further assistance.
