I-Firefox Community Forum

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?

I use Firefox as my default browser. When I click on a link in my apple mail it doesn't appear but when I right click to check the Firefox icon, it shows that a window should be open (call it mystery window). In the photo it's the "Settings". I cannot seem to access it. (It used to be that if I clicked it, it would open.) If I right click the icon I can open a new Firefox window but the one I originally tried to open still does not appear. That's how I opened this page. If I've opened a new window and I right click and select "Show all Windows" I can see the original window but I still cannot access it. I've tried quitting Firefox and shutting down my computer but when I restart my computer the Firefox icon still shows that the mystery window should be open. Still cannot access it.

This is a fairly new problem that started sometime in the last few months. i have an Apple computer.

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected). When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one. They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience. The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).

Here's some additional information and trouble testing we've conducted:

Uninstall and Reinstall of Fire fox

Check for updates (Updated to new version and still suffered the same issue)

Cleared cache and cookies

No extensions

Please if anyone has any advice or recommendations it would be greatly appreciated.

I made my post originally on the 3/9/26 but no one has gotten back to me, so I am creating another post.

Mozilla Firefox desktop : As at evening of 22nd May 2026, UK time, Firefox will not interface to Aol email. Gives " We can’t connect to the server at mail.aol.com ". Connection was fine earlier today, & as I know of no Mozilla changes, suspect this is a change at the AOL end. no longer permitting access to Firefox.  ?? Other browsers do connect, hence not an AOL outage.

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

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.

Каждый раз при попытке найти что-либо в интернете, выходит ошибка (фото прикрепил), очищал DNS и подключался к другому WIFI - браузер не работает. Помогите пожалуйста

After i installed firefox net jitter somehow appeared in my cs2. every time i play jitter is jumping randomly. Can yall somehow fix this i really enjoy using this browser but i just cant play with it running in the background((((

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 have noai.duckduckgo.com set as my default search engine. Almost always (but not quite every time) when I type anything into the address/search bar, I get a page with a "Server Not Found" error. (See attached image.) Refreshing the page immediately brings up the results without issue, but I consistently get the error first.

Oddly, if I go into settings and switch to a different search engine and then switch back to duckduckgo, the issue will briefly resolve and it'll work fine for a short while... and then I start getting the error again.

Is there any way to fix this?

I have the latest version 151.0.2 (64-bit), always update. It's terribly buggy now out of nowhere. Tabs won't connect to the internet after laptop wakes from sleep. All other browsers still do. If I close FF and reopen I lose ALL my tabs even though for decades I've had it set to reopen all tabs. What's up?

I was able to use Firefox web browser earlier today, but after trying to log in to Facebook, which failed, my account was no longer accessible, I saw an indication that my account was not connected. Do I need to update my software for Firefox. I've been having difficulties logging in to Facebook.

I open up firefox and the message appears - you must be signed into this network in order to access the internet. BUT i can use the internet. This is not a problem on a W10 machine which I also use.
