I am using 140 ESR version on linux with Cloudflare's DNS over HTTPS and with DOH active for some reason resolving a domain like d3oklwo3y1bx83.cloudfront.net will resolve to local host IP 127.0.0.1.

I am using firefox about:networking#dnslookuptool to test resolution of the domain d3oklwo3y1bx83.cloudfront.net Both with DOH on and off the resolution remains local host. I tried another browser on the same workstation and I was able to receive a resolution of 13.225.193.203 13.225.193.133 13.225.193.64 13.225.193.58 Why is firefox ESR not able to resolve that domain? What are causes ?

Is is firefox dnslookuptool results.

When I enable the firefox built-in vpn I have an error: "The proxy server is not found

Firefox cannot connect to the server at accounts.firefox.com What can you do?

Try to connect to another device. Check your modem or router. Log out and reconnect to Wi-Fi."

Thanks.

There are urls saved in my firefox which are not listed under "Manage Bookmarks". At least one is my own bookmark i already deleted. All others seem to be basically advertisement. Urls i never visited and don`t want suggested to me. I do not use a firefox account and my settings are set to only suggest my bookmarks in the url bar. How to remove this Garbage?

The latest version of Firefox 150.0.1 (64 bit) does not work correctly for Twitch.tv and Canadiantire.ca. I can't login to either. Is anyone else having similar problems?

I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

Your computer thinks it is May 1, 2026, which prevents Firefox from connecting securely. To visit www.olx.com.br, update your computer clock in your system settings to the current date, time, and time zone, and then refresh www.olx.com.br.

I am attempting to use Firefox's new built-in VPN to hide my browsing and use sites that are restricted like Reddit on a common wifi while I am on breaks. It worked on these common wifi systems for a little bit, but last week I believe, it just stopped working one day. Now, when I turn on the VPN, the only thing Firefox will do is display the following error: ~~~~~ Unable to find the proxy server

Firefox can’t connect to the server at [insert url here] What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi. ~~~~~ I was originally running Firefox 149 via snap on Ubuntu, but I just uninstalled the snap package and switched to 150.0.1 via the Mozilla APT repository and I am getting identical behavior. Is this just a bug, or is it possible the administrator here has explicitly blocked Firefox VPN? Is there anything else I can do about it, since connecting on a different device doesn't help me, I can't check the modem or router, and disconnecting and reconnecting does nothing?
