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 the last day or so, Firefox is refusing to resolve any web pages. I have had to write this in Safari, so I can't share the data from Firefox. Sorry.

Please help, thank you :)

I like the Firefox browser and Firefox was working fine for months but Firefox did ask me to do another update today. I did the update as requested and after the update Firefox will not connect to any websites on my desktop despite an excellent internet connection. I cannot find anyway to contact Firefox directly. For major problems such as a 100 percent failure rate to connect to any website, Firefox should provide direct help to the user as to the current major problem. I appreciate user ideas but Firefox should offer some help for major problems as the likely solutions can change over time. Hopefully if Firefox oversees user questions, someone at Firefox tech will at least respond to my question on this website or better yet contact me directly.

The problem may well be the update itself. The Firefox browser is working on my smartphone but not the desktop internet browser. I have some browser settings that I do not want to lose which a complete Firefox removal and reinstall would likely cause. Any suggestions from fellow Firefox users are appreciated and I look forward to them. Have other Firefox users experienced this major problem?

Thank you.

I am on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.

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?

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.

Mailfence.com is my email provider. I've been with them for years. Two weeks ago I am suddenly unable to connect with the website. My ISP is Comcast. My next door neighbor also uses Comcast. He can get to mailfence.com just fine. Can you please help with this issue. Comcast has declined to provide any help. Thanks.........Bob Horning

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.
