Firefox Community Forum

Starting on Wednesday, 8/19/26, Firefox ceased working on my Windows 11 computer (it still works on the Windows 7 computer). One possible problem is the 1Password extension I added recently. However, it worked for a few days with the extension with no problem. The other suspect is a change to Firefox. On Wednesday morning when I opened Firefox there was a message that I could now stream games directly on Firefox. It has never worked since I got that message. Does anyone have any ideas what I can do to get Firefox up and running again?

I need help with an issue and would like guidance on how to resolve it. I can provide relevant details, including what happened, any error messages, what I’ve already tried, and the steps needed to reproduce the problem.

Create custom DNS providers list to "DNS over HTTPS" "Choose provider" menu (Settings > Privacy & Security - DNS over HTTPS) This can be applied to any Mozilla based browser.

1. Write about:config in url-bar and press [Enter].

2. In the "Search preference name" box Find the "doh-rollout.provider-list" value.

2.a. Create it if not exist by choosing: "String" value and press "+" (add). 2.b. On the right side of the value, Write the '*one string code'. - (if a code already exist, select all code [Ctrl+A] & copy [Ctrl+C] and paste [Ctrl+V] in a notepad and Save it so to keep backup with the previous setting.)

The '*one string code': [ { "UIName": "Cloudflare: Mozilla uri: (https://mozilla.cloudflare-dns.com/dns-query)",

You can modify the code based on your preferences to change the "Choose provider" menu list.

I am trying to log on to my bank website but it requires something other than Foxfire to log on. I can't figure out how to logon. Can you help? Says my browser needs updated and is no longer supported. I have windows 10 I think.

I have not been able to sign on to my bank account nor yahoo account?

Have changed passwords, still no help?

I have Avast Security...no problems there?
