I am receiving "The page isn't redirecting properly - Firefox can't connect to server" error messages. This happens on nearly every website repeatedly for the last six? weeks. It does not happen in other browsers i.e. Chrome. I click the "Try Again" button in the Firefox error msg popup window over and over, 3-14+ times, to get past the error msg and access the site. When I try to login to many sites I am kicked out to the same error msg. Also kicked out of sites randomly when trying to navigate to another page on the same site. I had Claude AI take me step-by-step through all of the trouble shooting and adjustments to various settings. All of my extensions are off. I have had my ISP re-initialize my modem and I've run antivirus scans, still the problem persists. (Strangely YouTube does not have these problems) I love Firefox. I've got it setup just the way I like it. I have been using it for 20 years and during those two decades Firefox has been stable and had only minor glitches. I do not want to change my browser. Chrome feels clunky to me. I'm attaching three representative screen captures of the error msgs. Looking forward to anyone's help.

Bonjour, depuis la mise à jour je ne peux plus me connecter sur mon NAS.

Il semble y avoir un problème sur ce site

Firefox ne peut pas se connecter au serveur à l’adresse .....

Par contre je peux me connecter depuis Safari donc le problème semble venir de Firefox.

ein nettes Hallo,

seit einiger Zeit habe ich Probleme das Firefox die Verbindung zum Internet verliert. Andere Browser wie zum Beispiel Google haben diese Probleme nicht. Ich habe Firefox neu installiert, den Cash geleert und auch schon mit dem Fehlerprogramm von euch laufen lassen, es wird nicht besser, vielleicht kennt ihr noch eine Lösung die mir helfen kann...

Beste Grüße,

Axel Lulies

Setup: macOS Tahoe (26.4) and Firefox 149.0

=

Behavior: Out of the blue this morning, every website I try to visit in Firefox returns "Looks like there’s a problem with this site". Every other browser works fine.

Things I've tried, that haven't fixed it: - Ruled Out DNS: Sites like 1.1.1.1 and my home router's IP return the same issue in Firefox, but also resolve in any other browser. - Firefox Safe Mode: no fix - Deleted All Settings, Reinstalled Fresh: - Removed the Firefox App, deleted:

       - ~/Library/Application\ Support/Firefox
       - ~/Library/Caches/Mozilla
       - ~/Library/Caches/Firefox

...and then downloaded and installed 149.0 fresh. - Refreshed Firefox (via [link] - about:preferences (toggled between FALSE and TRUE, testing each time) via this YouTube video

- network.dns.disableIPv6

- network.dns.disablePrefetch
- network.dns.disablePrefetchFromHTTPS
- network.dns.disable

....and in desperation, I checked my Mac for Malware (clean)

I'm at a complete loss: every other browser works, but Firefox is a 100% fail for all websites. Any thoughts?

My hotspot is constantly disconnected by Firefox. I have the latest browser. And if this cant be sorted Ill have to go back to google. Its a nighmare. Firefox keeps giving me a wired connection

how do i delete or remove the message about could connect error

Contributor note: See also /questions/1576275 for the detailed error message.

Hey,

after looking through many Forums and solutions on the internet, nothing can resolve my issue, so i hope this one can help. I just switched to Firefox and have the reaccuring problem, that i cannot load sites, that are located in my local network (e.g. homeassistant.local; 192.168.8.265:2283).

I always get a "server not found" error from firefox and the certificate information, that i am communicating through an unsecured connection (haha, yes good joke firefox. I know my local services do not all have an SSL certificate.) I already tried altering settings for Proxy, DNS over https, MACos Safety settings but nothing helps. I am jsut looking for that one "trust this domain" button, that i get on 'ALL OTHER BROWSERS like Chrome, Safari and Edge...

P.S.: All the services are up and running and i can reach them through any other Browser.

when i open microzain website he give me these error

Server Not Found

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

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

All of a sudden I am finding that Firefox will not connect me to certain websites such as Walmart, Doordash and even Firefox itself. It looks like it's trying to but it just gets stuck. What's causing this and how do I fix it?

Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

Good Morning,

my Firefox /Mac OS blocks my NAS in my local network. otherwise I can contact my NAS via Firefox / Ipad OS. Where´s the problem, Firefox kann sich nicht mit dem Server auf 192.168.178.112 verbinden

I don´t find any switches to change.

For the last ~6 months, my Firefox Windows build has been stuck connecting to numerous websites. Whether I enable auto-detect proxy settings or no proxy settings at all, the same result happens. The websites hang and do not resolve. Occasionally, some of the new Firefox releases have improved this, but then they revert to not working. I'm about to give up on this platform and switch entirely to Chrome which never has this problem.

Has anyone else experienced this? How if at all have you been able to fix it?

Every time I start Firefox lately, it keeps prompting me: "You must log in to this network before you can access the Internet." I have no idea what this means and have no problem accessing the Internet in any case. What suddenly started causing this !#@%$ message and how do I turn it off?
