Firefox Community Forum

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.

Free Firefox VPN hit 50 gb limit - so purchased Mozilla VPN for a year - worked fine but now Firefox kicks out any website attempt - Mozilla says not there problem but a Firefox problem - they are same company

What setting is wrong?!

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.

Server Not Found

Firefox can’t connect to the server at www.rt.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).

This is the second day my Firefox browser has periodically dropped connectivity on my Mac. When I switch to Chrome, it connects fine, so it's clearly the browser, not my WiFi. I updated my Mac to the latest software. I tried changing proxy settings and deleting cookies, but nothing has helped.

Have used this wi-fi before on Fedora Workstation 44. Reinstalled linux using Xfce Fedora 44. Selected now from list of available wi-fi connections and indicates connected at 79%. Firefox not able to use connection? Thanks for any help available.
