Firefox Community Forum

Sometime in the last week or two, every page starts with a banner that says "you must sign in to the internet to continue". I'm already/always signed in. On those few occasions when I click on the network login link (rather than clicking X to dismiss this dangerous and wrong banner), it shows a very dangerous site and says that site is prohibited. (As it should be.) So why is the banner demanding that I log in (forcing me to click X to dismiss it)? This feels like your site has been compromised, that some malicious actor is forcing this prompt on every page. (And even after I click X to dismiss it, it reappears 10-15 minutes later.

Why is my location never accurate? It is off by 200–300 kilometers. I am currently in Mae Sot District, Tak Province, but my GPS location shows that I am in Phitsanulok. !?

Firefox is my default browser. Today I attempted to access several different sites and I keep getting a message that Firefox can't find the site. My other browsers have no trouble at all. Something went awry with Firefox. Is it beyond my puny actions to resolve? Do I need to reload Firefox somehow? I can't back anything up because I don't have access to it in the cloud. What am I to do?

Thank you.

Hi, I don't know what is causing this issue but I cannot click on links (on desktop) from my emails it just takes me to a blank page that can't load saying Server not found. I can click on the links using my mobile app. Is this a Firefox issue?

I have tried with Firefox and Waterfox, (I don't use Chrome, Edge etc). I am using gmail.

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 recently switched from Debian to Fedora Workstation. Everything works fine, even better under Fedora, except Firefox. There is this quirk, where whenever I wake up my system from suspension, and I try to search something, Firefox just shows a loading sign as if it was loading the page, but I see via the inspect tool that it isn't even sending any HTTPS requests to the server. I know this problem specifically affects Firefox, because other programs that require an internet connection, such as fetching mail via Thunderbird or installing packages via DNF work completely fine. In order to get Firefox to actually work, I have to completely close and reopen the application, forcing me to lose unsaved work in some cases. I've tried everything, from restarting my machine to waiting to see if it will be patched in a future update, but nothing has gotten better. Please help me. Thank you in advance.

I'm not a tech savvy user. Although I am using a personal network could Mozilla be interfering with the link of my Linux computer to the HP printer? Any suggestions on how to remedy this?
