Key notes

You have stumbled upon this guide because you encountered the errorHmm we’re having trouble finding that siteon Firefox. Let us walk you through some important elements.

Looking at the current numbers, Mozilla Firefox is the greatest alternative to Google Chrome. After Mozilla revitalized its native browser with the Quantum update, Firefox retook its rightful place.

So if you have stuck to this browser and this error puts you off, let us walk you through possible causes and the most reliable solutions.

Why does Firefox error Hmm we’re having trouble finding that site appear?

This error message in Firefox typically indicates that the browser cannot establish a connection to the website you’re trying to access. This can happen for any of the following reasons:

Quick Tip:

Before committing to try and fix Mozilla Firefox, maybe you should consider replacing it altogether or at least using another browser until you fix it.

A great alternative is Opera One. This web browser uses the same source code as Google Chrome and Edge, namely the Chromium engine.

How can I fix Hmm we’re having trouble finding that site error?

1. Reset the network settings

Once done, restart the computer for the changes to effect and check if theHmm. We’re having trouble finding that site.Firefox error is fixed.

2. Run the dedicated Troubleshooter:

Connection issues are always difficult to deal with due to a variety of possible reasons why the network is down. Maybe it’s on your side, or maybe it is the ISP. So, it’s best to let the dedicated troubleshooter do all the hard work.

3. Clear Firefox’s cache

Firefox, like any other browser, collects a lot of cached data. Besides the browsing history, it’ll collect cookies that store the website data.

The intention here is to speed up your surfing experience, but cookies can, when pilled up, cause issues within the browser. We recommend clearing all browser-stored files and trying to connect again.

Just don’t forget to back up your passwords, as this procedure will delete those, too.

4. Use the Troubleshoot Mode to identify issues

Firefox will now launch with the extensions and other customized items disabled. Now check if you can open the websites that were inaccessible before. If that’s the case, one of the disabled items likely caused the issue. So, we will now start disabling the extensions.

Before you proceed, close theTroubleshoot Modewindow and launchFirefoxnormally.

If nothing else worked yet to fix theHmm. We’re having trouble finding that site.Firefox error, disabling the add-ons might help. This especially applies to proxy/VPN extensions that hide your IP address and replace it with the public one.

They are only browser-based; in my experience, free options never worked for me. They either have a low data limit or slow down the bandwidth substantially.

Paid solutions are much better but still fall short compared to VPNs.

5. Disable IPv6, Proxy, and DNS prefetching

Mozilla Firefox works with IPv6 rather than with IPv4. If you’re solely sticking with the IPv4 protocol, we recommend disabling the IPv6 in Mozilla Firefox.

This should avoid further issues, and the abovementioned error should be addressed. In addition, if you don’t use the general Proxy server settings, we suggest disabling this option.

And finally, disable the DNS Prefetching. This feature allows Firefox to load uncached sites faster.

6. Reinstall Mozilla

A better way to uninstall Mozilla Firefox is if you use a dedicated third-party uninstaller since it will eliminate the program itself and any residual files that it may otherwise leave behind.

We recommend picking one of thebest uninstaller softwarebecause they are proven completely safe. They affect nothing else on your PC besides the apps you want to remove.

On top of that, most worthwhile uninstallers come with additional optimization features that help your PC run smoother. They are easy to use and will eliminate possible errors when reinstalling.

That should do it! In case you’re still encountering theHmm. We’re having trouble finding that site.Firefox error, we recommend sending a ticket to Mozilla support.
