Firefox won't load any webpages. Every website I try to open fails to load, even though my internet connection is working. I have restarted Firefox and my laptop, but the problem till exists. I am using a Lenovo laptop. Please help me fix this issue

Server Not Found

Firefox can’t connect to the server at www.ped.ucd.ac.ma. What can you do about it?

   Check to make sure you’ve typed the website address correctly and try again in a few moments.
   Check your network connection.
   Check that Firefox has permission to access the web (you might be connected but behind a firewall).

I asked a question last night about whether or not Firefox had an IP Address. Sounded silly, but I was dealing with an unfamiliar IP. I did eventually find apps that locate IP Addresses. Problem solved . Just want to thank James for taking the time to respond to my question.

Hello

I downloaded FF 152.0.6 update and my internet went immediately down (Windows 10, 64 bit). Internet box working, Wifi working, Android mobile receiving internet. Once removing the 152.0.6 by system restore, internet worked again. Anybody reported this or have a solution? Thank you

Whenever I load Firefox, for the first minute or so, or the first X attempts at loading (any) website, I just get "Can't connect to server" errors. Eventually it does connect and then has no more issues, unless I close the browser and open a new one, then the process begins again.

New Alienware laptop with a fresh windows 11 install.

Other browsers are working fine, this is isolated to this browser, on this device only.

Things I have tried:

All the suggestions in the connectivity help section Uninstalling Firefox > Deleting my profile data from laptop > Cleaning registry > Deleting anything else that searching for "mozilla" turned up > Clean install without logging into any profile or enabling sync or importing anything (somehow still knows there was a previous install though, just doesn't import anything)

Still the same results.

I've used Firefox for probably a decade now and I am truly loathed to have to move to Chrome, but if I can't find a solution this is just untenable. Any help would be much appreciated!

Im not sure when the issue first started as Firefox updates quite often. Here is the issue: When logging into my router settings page locally,(http://xxx.xxx.xxx.xxx to access router on network), the forms constantly overlap. For example there is a form on the left that shows each settings page and the form on the right which is the settings i currently have selected.

When each settings form is loaded it is overlapped by the form on the right. To fix it i zoom in or out. And the forms re-align. But then they almost immediately snap back making it almost impossible to enter any data. This has not been an issue in the past, but i havent had to adjust my router setting for a while. It's driving me insane, so much that i installed a chrome browser just to access my router info. But i would prefer to use firefox as i do not like chrome.

This is also on both an old install and a brand new install of windows 10 and new install of firefox.

The router is a c4000bg from centurylink.

Thank you for any assistance in the matter.

I attended a conference and can't open any of there links due to the fact it is on the cloudfare program???? website is https://s3.us-east-1.amazonaws.com/RETA/2026/files/index-table-2026-mid-year-update-.xlsx and the message

this is what I get back each time and I have never had this happen before:

Server Not Found

Firefox can’t connect to the server at s3.us-east-1.amazonaws.com. What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

I have just download firefox, but I can't browse any web on firefox. Then, I tried firefox ESR, it doesn't work eather. Only setting page can be open. Microsoft Edge can work well (image 1 left is Edge), and my internat is OK, only Windows Defender work.
