Firefox: форум сообщества

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?

Have been a Firefox user for many years and have always been able to connect to my NAS with any problem. Today that option has now disappeared and I get the dreaded "Looks like there’s a problem with this site" page. I am a Mac user updated to 26.4. and the latest Firefox update. The NAS is working well and I am able to connect without problem using Safari but I am a Firefox user and do not wish to change. Can anyone offer a solution Thank You

In the last 48 hours I haven't been able to access the following - https://www.co-operativebank.co.uk - they do not appear to be the problem - when I try the link the 'retrying' symbol on the top left of screen (?taskbar), flashes extremely rapidly and it appears the system can't find the website. Are you aware of this issue.

I installed firefox a week ago, now in the middle of creating a x account I no longer can reach the internet on this browser, edge works, chrome works. IT SAYS AT THE TOP YOU MUST LOG IN T THIS NETWORK BEFORE YOU CAN AS THE INTERNET. IT LET ME CREATE 1/2 OF A X ACCOUNT.

Is this the reason millions of people are leaving firefox as AI has indicated? The fix is apparently try this for 2 pages. Please create a trouble shooting tool within firefox to fix this junk and I am deleting firefox, don't worry I will reload it 1 - 5 years and try again as I did 1 -5 years in the past.

I am investigating a persistent geolocation issue affecting Firefox, where the browser geolocation API returns a precise but incorrect location in the United States.

Actual location: United Kingdom (precise location not shared for privacy)

Incorrect location returned: 39.264542, -76.765924 (Catonsville, Maryland, USA) Reported accuracy: approximately 185 meters around this incorrect point

This issue has been extensively tested and does not appear to be related to IP geolocation, system configuration, or local network setup.

Summary of findings: Reproduced in Firefox and across other browsers:

Mozilla Firefox Microsoft Edge Google Chrome Brave

Reproduced across multiple systems: Windows 11 Windows Server 2025

Reproduced across multiple public IPs: Static /29 allocation BT dynamic IP (completely different address) → Same incorrect Maryland location returned in all cases

Wi-Fi vs Ethernet: Wi-Fi (with SSID/location services) returns correct UK location Ethernet consistently returns Maryland → Indicates fallback to provider-based geolocation rather than IP-based resolution

All standard IP geolocation sources are correct (UK): ipinfo.io ifconfig.co DB-IP / BrowserLeaks IP lookup RIPE allocation Reverse DNS (BT Openworld)

Command-line and non-browser tests confirm correct UK location: curl / PowerShell requests return UK consistently No evidence of US routing, proxying, or DNS leakage

Critical observation: Firefox geolocation (navigator.geolocation) returns:

Exact same coordinates every time Same result across all browsers and machines Consistent high-precision accuracy (~185 meters) around the incorrect Maryland location

Control comparison: Pale Moon (more IP-based geolocation path) returns correct UK location

Conclusion: This does not appear to be a traditional IP geolocation issue.

All IP-based systems resolve correctly to the UK. The incorrect result only occurs when using browser geolocation APIs.

Given: The consistency across browsers and systems The identical coordinates returned each time The high-precision accuracy around the incorrect location

This strongly suggests a provider-side geolocation dataset issue.

Since Firefox uses Mozilla Location Services, I would like to confirm whether:

This result is coming from Mozilla Location Services directly, or from an upstream/shared dataset Whether this type of persistent incorrect high-confidence location can be corrected or escalated within Mozilla’s geolocation system

Thank you.

I can't access FSIS website which I need to do so for my job. This is what I get

"Firefox can't connect to the server at usda.gov Try connecting with a different device Check your modem or router Disconnect and reconnect to Wi-Fi"

I can't do any of those things because they make absolutely no sense. Nothing is wrong with my router, Wi-Fi. It's your program.

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!
