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.

Hello Firefox Support Team,I am facing a persistent issue where Firefox is unable to open or connect to any Public IP addresses, resulting in a "Connection Reset" error. This issue happens simultaneously on two different operating systems: Windows and Linux (on the same network).Interestingly, the same Public IP addresses open completely fine and without any issues on Google Chrome.I have already tried the following troubleshooting steps, but none of them resolved the issue:Disabled HTTPS-Only Mode completely.Disabled Secure DNS (DNS over HTTPS).Changed Network Settings to "No Proxy".Set "security.tls.version.min" to 1 and enabled deprecated TLS.Disabled HTTP/3 and HTTP/2 in about:config.Performed a full Firefox Refresh (Safe Mode / Default Profile).Since the issue persists across different OS platforms only on Firefox, it seems to be related to how Firefox handles direct IP handshakes compared to Chromium-based browsers.Please advise on how to resolve this. Thank you.

I guess I'm hoping an engineer or someone who works on firefox can resolve this cause it's always what pushes what me away.

I'll be sick of Chrome harvesting all my data, I'll download firefox, and I'll set it up. A couple years ago I deleted my chrome profile and switched completely over to firefox. I want to say once a month, I'll open firefox and websites won't load. If they preload they'll act like they're offline.

It's happened to me on Windows machines and Mac machines.

If someone wants to seriously drill down and figure out why this happens across platforms and DECADES, I am happy to provide logs and video chat or something.

Firefox ran all right, i.e. accessed anywhere in the world. But after I specified Express VPN to apply VPN to Firefox, Firefox stopped finding sites as if it lost name resolving ability. When I did a similar thing for Google Chrome or Microsoft Edge, such things did not happen.

I can not get web sites to load on my computer in windows 10 on fire fox. Whats wrong? Its been this way for a while now. I just get an error message. Why. Little thing just toggels back and forth no loading. Why?

Firefox stops loading websites after Mac lock/unlock I am using a MacBook with Apple M1 and Firefox 151.0.2 (aarch64). Whenever I lock my MacBook and unlock it later, or leave it idle for a longer period and then log back in, Firefox stops working properly. It appears to stop resolving DNS requests. Every website remains stuck with messages such as **"Waiting for http://..."**, and no pages load. This issue affects all websites. At the same time, Chrome works without any problem and is able to load the same websites successfully, which suggests that the network connection is working correctly. The only workaround is to force quit Firefox and start it again. After restarting, everything works normally until the next lock/unlock cycle. This issue occurs consistently after the Mac is locked or left idle for an extended period. It is significantly impacting my productivity and reduces the reliability of using Firefox as my primary browser.

Please suggest the way to fix this.

Sir, Unable to connect

Firefox can’t connect to the server at eforms.assam.gov.in What can you do about it?

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Note:- I have connected my pc with wifi .Kindly solve the issue please.

Hello

I downloaded FF 152.0.6 update and my internet went immediately down (Windows 10, 64 bit). Internet box working, Wifi working, Android mobile receiving internet. Once removing the 152.0.6 by system restore, internet worked again. Anybody reported this or have a solution? Thank you

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.
