I am trying to be nice but it's should be going both ways . Server Not Found. Firefox can’t connect to the server at www.rebaid.com. AND YOU GIVING ME ADVICE: "Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi." We both know that my router is not the problem nor my PC/device. It's you and you should harder to connect me with a page-site.

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

Issues with redirect. A group I am a member of uses Constant Contact. An email is sent with a link to a report. Receive this error:

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.

No matter what site I try to load or search it says unable to connect firefox cant connect to server at ( whatever site this could be google yahoo or other sites not just search enjoins , anything I try ) Under this it says what can I do about this and gives me a few options. The problem I think had to do with firefox not being able to connect or no longer having permission to the web. I can connect to everything if I use another browser it’s just fire fox and it happened randomly. It was fine until it wasnt please help I want to use fire fox

Today (7/11/26) Mozilla VPN began blocking all access to the Internet. When I turn it off, I can connect. When I turn it on, I can't. Am I the only one? So far I have:

• Reset the app
• Uninstalled all WAN network adapters and restarted (I notice for the first time that Mozilla Tunnel appears in the list after doing this)

It is interesting to note that Proton free VPN which I installed as an experiment, and ran with Mozilla VPN entirely off (system tray quit as well) also blocks all Internet traffic. So it could be one of those Windows update issues. This afternoon, all was well. I turned off my machine, turned it back on, and no browsing can happen with either VPN on.

Normally, Mozilla VPN works flawlessly, so I have no complaints--it's only a technical mystery to unravel.

I changed ISP's this week and my computer connects via Ethernet cable through my router. I have no real issues accessing the internet. But after waking from sleep or restarting, Firefox displays the network login prompt. How do I get rid of it? Thanks.

Starting today (7/8/26), Firefox opens with a "cannot connect" message, have tried multiple online suggestions including downloading and "reinstalling" but nothing works

I'm experiencing an intermittent issue with Firefox and I'm trying to figure out what might be causing it.

Occasionally, Firefox stops loading pages in new tabs. If I open a new tab and try to navigate to any website, it won't load, it'll state "waiting for www.[anywebsite].com" forever. However, if I use a tab that was already open before the issue started, I can still navigate to different websites from that tab without any problems.

The only reliable fix I've found is to completely close Firefox and start it again.

One strange thing I've noticed is that, sometimes while this issue is happening, if I put my laptop to sleep and then wake it up again, Firefox starts working normally, including in new tabs, without needing to restart the browser. But this isn't a something that works everytime.

I've already gone through the troubleshooting steps in the Mozilla Support article "Firefox can't load websites but other browsers can", but none of the suggested solutions resolved the issue.

I also tried disabling all my extensions, one by one, but the problem still occurs.

Has anyone seen this behavior before or knows what could cause it?

Additional information:

Firefox version: 152.0.2 (64-bit) (currently shows an available update requiring a restart, but it never seems to update even when enforced restarting) Operating system: Windows 1p Pro Version 10.0.18363 Build 18363

I'd appreciate any answers

I have Mozilla VPN installed on my computer, but not in Firefox. Recently, whenever I turn the VPN on or off, the tab I have open in Firefox reloads. This usually doesn't matter, but sometimes it's really annoying, like when I'm really deep in an infinite scroll website. I want to turn it off, but I tried turning accessibility.blockautorefresh on in about:config, and it still does it. I don't want to blindly mess with settings when I don't know what they do. Does anyone know if there's a setting/group of settings I can use to stop Firefox from reloading on network change?
