I had a proxy set manually before and it was working just well, after I updated firefox it stopped asking for username password for my proxy and I keep getting no network error on every website I check. I also reentered the proxy data again and checked somethings in the about:config page to be true but still doesn't work.

Almost every internet site that I go to using Firefox I get this message, "Hmm. We’re having trouble finding that site.". When I use Google Chrome or Microsoft Edge, I can get to the site? I really like using Firefox, but if it does not work?

Every time I try to access Citbank to view my account I get a screen that says "Failed Connection". How can I stop this? This is "CITBANK" not Citibank. Thank you for your time.

Within a minute of starting Firefox up, it loses internet connection and prevents the computer from connecting to anything else. Using Ethernet or Wifi doesn't work. The only thing that corrects it is restarting the computer. List of things we have tried: Troubleshooting Mode in Firefox Removing all addons Uninstalling and Reinstalling Firefox with the latest update Disabling DNS over HTTPS Clearing Firefox's DNS cache Clearing the computer's DNS cache Adding IPv6 to our standard IPv4 connection Rebooting the router Used a new Firefox profile Run a virus scan

This is on Windows 11. There are multiple other computers on the network, with W10 and W11, and none of them are having this issue. I've tried everything I can think of. After losing connection, it still pings 8.8.8.8.. Is there anything else we can try?

For so, me reason i have lost my connection to FireFox. It was in the last week. I was surprised because i have been using it for a few years. Can you help me to be able to use it again please?

Ever since upgrading to Windows 11, my Firefox installation has occasionally been unable to resolve domain names of some websites. Example domains:

• apps.powerapps.com
• static.cdninstagram.com
• google.com

As I was trying to debug this, I discovered that the DNS resolution and connection timings are just over 30 seconds (see the attached image). This is highly unusual.

• The issue does not occur with other web browsers on my computer (i.e., Microsoft Edge).
• The issue has persisted across reboots.
• I have already reinstalled Firefox (and wiped the temp files and appdata profile before installing again).
• The issue does not occur with other devices on my home network.
• DNS over HTTPS has been manually disabled.
• Changing DNS resolvers in my Windows settings does not fix the issue.
• The issue is still present with a fresh, unmodified installation of Firefox.

Any help would be greatly appreciated! I love Firefox and do not want to switch to a different browser.

Hmm. We’re having trouble finding that site.
