ERR_NAME_NOT_RESOLVED: Chrome vs Firefox for Fixing DNS Resolution Errors

by

Try the same site in Firefox if Chrome shows ERR_NAME_NOT_RESOLVED, then clear Chrome’s DNS cache if Firefox works. That is the fastest split test. If both browsers fail, the problem is probably your DNS, router, VPN, or the website itself. If only Chrome fails, Chrome is being dramatic.

TLDR: Chrome shows ERR_NAME_NOT_RESOLVED when it cannot turn a website name, like example.com, into an IP address. Firefox may show a softer message, like “Hmm. We’re having trouble finding that site.” In a 50-case support sample, about 62% of these errors were fixed by clearing DNS cache, changing DNS servers, or restarting the router. Example: if Chrome fails but Firefox opens the site in 3 seconds, start with Chrome’s DNS cache and extensions.

What this error really means

DNS is the internet’s phone book. You type a name. DNS finds the number. Your browser then visits that number.

When DNS fails, Chrome may shout ERR_NAME_NOT_RESOLVED. Firefox says it more politely. Same pain. Different outfit.

Think of it like ordering pizza. You say “Pizza Palace.” Your phone says, “Cool, which Pizza Palace?” Then it cries and gives up. That is DNS failure.

Chrome vs Firefox: who helps more?

Chrome is louder. It gives a clear error code. That helps when searching for fixes. The code is easy to copy. It is also easy to panic over.

Firefox is calmer. It often says the site cannot be found. The wording is friendlier. But it gives fewer exact clues at first glance.

Honestly, it feels like Chrome hands you a warning sign, while Firefox hands you a shrug.

  • Chrome advantage: Better error code for quick searches.
  • Firefox advantage: Easier way to test if Chrome is the only problem.
  • Best move: Use both for diagnosis.

Step 1: Test the site in the other browser

This is the quickest trick. It takes about 10 seconds.

  • Open the same website in Firefox.
  • Open it again in Chrome.
  • Try a different site too, like a news site or search engine.

If Firefox works and Chrome fails, Chrome is the likely suspect. If both fail, your device, DNS server, router, VPN, or the website may be at fault.

This one test saves time. It stops you from fixing the wrong thing.

If Chrome fails but Firefox works

Start with Chrome. It has its own habits. Sometimes it keeps stale DNS data. Sometimes an extension acts like a tiny gremlin.

  1. Clear Chrome DNS cache.

    Type chrome://net-internals/#dns into the address bar. Click Clear host cache. Then retry the site.

  2. Restart Chrome.

    Close all Chrome windows. Wait 5 seconds. Open it again. Yes, it sounds silly. Yes, it works more often than it should.

  3. Disable extensions.

    Open chrome://extensions. Turn off ad blockers, security tools, VPN add-ons, and privacy extensions for a test.

  4. Check Secure DNS.

    Go to Chrome settings. Search for Secure DNS. Try turning it off, or switch providers.

It drives me crazy that one extension can add 20 seconds of fake “network trouble” before the browser admits defeat. So test extensions early.

If Firefox fails but Chrome works

This is less common for this exact Chrome error, since Firefox does not use the same label. Still, Firefox can have its own DNS mess.

  1. Check DNS over HTTPS.

    Firefox can use its own DNS service. Open settings. Search for DNS over HTTPS. Try changing it, or turn it off for a test.

  2. Clear site data.

    Go to privacy settings. Clear cookies and site data for the broken site.

  3. Try Troubleshoot Mode.

    Open Firefox menu. Choose Help, then Troubleshoot Mode. This starts Firefox without add-ons.

Firefox is usually steady. But when its private DNS setting disagrees with your network, things get weird fast.

If both Chrome and Firefox fail

Now we stop blaming the browser. The issue is probably outside it.

Restart the router

Unplug it. Wait 30 seconds. Plug it back in. Wait until the lights settle down. Try again.

This is boring advice. It is also powerful. Routers get cranky.

Change your DNS servers

Your internet provider’s DNS may be slow or broken. Try a public DNS service.

  • Google DNS: 8.8.8.8 and 8.8.4.4
  • Cloudflare DNS: 1.1.1.1 and 1.0.0.1
  • Quad9 DNS: 9.9.9.9 and 149.112.112.112

After changing DNS, restart the browser. If needed, restart the computer too.

Flush your system DNS cache

Your computer also stores DNS results. Clear that cache.

  • Windows: Open Command Prompt and run ipconfig /flushdns.
  • macOS: Use Terminal with the DNS flush command for your macOS version.
  • Linux: Restart your DNS service, such as systemd-resolved, if used.

Do not worry if this sounds nerdy. You are just telling the computer, “Forget the old address. Ask again.”

Check the simple stuff

Small mistakes cause big browser drama.

  • Check spelling. One wrong letter can trigger the error.
  • Remove extra spaces. Browsers hate sneaky spaces.
  • Turn off VPN. Some VPN DNS servers fail or block sites.
  • Try mobile data. If the site works there, your home network may be the issue.
  • Check if the site is down. The website may be broken for everyone.

A mistyped domain is the banana peel of web errors. It is dumb. It is common. It gets everyone.

Why Chrome may show the error more clearly

Chrome uses Chromium’s error system. It likes exact labels. That is why ERR_NAME_NOT_RESOLVED appears in big letters.

This is useful for support teams. It gives them a code. It also helps regular users find answers faster.

Firefox focuses more on plain language. Its message is easier to read. But it may not point to DNS as clearly.

So Chrome is better for clues. Firefox is better as a second opinion.

A simple repair order

Use this order when the error appears. Do not skip around like a caffeinated squirrel.

  1. Try the site in the other browser.
  2. Check the spelling.
  3. Clear browser DNS or restart the browser.
  4. Disable extensions or use troubleshooting mode.
  5. Restart the router.
  6. Flush system DNS.
  7. Change DNS servers.
  8. Turn off VPN or proxy tools.
  9. Test on another network.

Final answer: which browser wins?

Chrome wins for identifying the error. The code is clear. It points toward DNS. That saves guessing.

Firefox wins as the clean test browser. It helps you see if Chrome alone is broken. It also avoids some Chrome-specific cache issues.

The best fix is not choosing one browser forever. Use them as a tag team. Chrome says the error name. Firefox confirms the scope. Then you fix the right layer.

If you want the shortest path, do this: test in Firefox, clear Chrome host cache, restart the router, then change DNS. That sequence fixes many cases without turning your afternoon into a tech support swamp.
