Firefox Community Forum

Hi. Recently I have been having issues connecting to various websites including ones that I have connected to in the past. The first one that I noticed that I could no longer connect to was The Trek (https://thetrek.co/) which I have for several years had no issue connecting to. Now it is happening with various other websites. I want to continue to be able to access the blogs etc. on their website. Thank you!

Hei!

I have used firefox.localhost to test my html page containing some JavaScript.

Now suddenly (it has worked nicely many times) it claims that there is not connection:

I also tried the "BlueFox" (developer version) and the response was exactly the same.

Firefox was just yesterday updated. OS is Windows 11.

Here the response text:

" Unable to connect

Firefox can’t connect to the server at firefox1.localhost What can you do about it?

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web

Server Not Found

Firefox can’t connect to the server at legalfolder.sce.com. 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 am currently having a challenge browsing my offline videos downloaded on YouTube, and I noticed this since I recently updated my Mozilla browser. Formerly, even when my internet is down, I could open YouTube, and it would take me to my offline downloaded video, but now, when I am offline, it just shows Check your internet connection.

For the pas 2 mouths i am getting random: "Server Not Found.Firefox can’t connect to the server at" It is happening on random sites that i know for sure they are not down... Waiting , closing fire fox and open it again, refresh but after waiting... helps.

My Firefox on a Linux system only connects to my gmail acount. Any other attempt to connect to sites gives the msg Can not connect to Server. Do I need to reset something? Or reload the Linux system. Thanks Graham Benson

I start FF in safe-mode. I open a local page which includes only one URL. When I hover on this link I see (`tcpdump`) a DNS lookup being performed for this domain. I followed the suggestions from Mozilla but I still see this.

How do I stop this access.

I use FF "156.0 (64-bit)" on Fedora 44.

TIA

Firefox upgraded this morning. I can't connect to any of my URL's. I have rebooted my computer, went and closed all open Firefoxes, and Run as Admin. I can connect changing to Run as Admin once then I can't connect to anything else. If I open Chrome - there is no issues. How can I get back to where it worked?

I am using Windows 10 . I have MS Edge as well as FireFox browsers installed. I just recently installed Thunderbird.

Since I used FireFox and turned FireFox VPN on and then off (after about 15 minutes) I cannot connect to some websites like rockauto.com using FireFox or MS Edge. If I turn FireFox VPN back on I can connect to these sites (rockauto.com is only one example) just fine. But if I exit FireFox and go to use MS Edge -- I cannot access the websites at all, they timeout.

What gives?

When i am using my home wifi, firefox can connect no problem. When using a public wifi or school wifi it struggles to load into any site. I have tried adjusting the proxy settings and erasing any cache and restarting my laptop. I cant even update fire fox because it cant download the update.
