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.

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.

Unable to connect

Firefox can’t establish a connection to the server at vbgramgde3.dord.gov.in.

   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.

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.

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.
