Within a minute of starting Firefox up, it loses internet connection and prevents the computer from connecting to anything else. Using Ethernet or Wifi doesn't work. The only thing that corrects it is restarting the computer. List of things we have tried: Troubleshooting Mode in Firefox Removing all addons Uninstalling and Reinstalling Firefox with the latest update Disabling DNS over HTTPS Clearing Firefox's DNS cache Clearing the computer's DNS cache Adding IPv6 to our standard IPv4 connection Rebooting the router Used a new Firefox profile Run a virus scan

This is on Windows 11. There are multiple other computers on the network, with W10 and W11, and none of them are having this issue. I've tried everything I can think of. After losing connection, it still pings 8.8.8.8.. Is there anything else we can try?

Firefox has started crashing immediately upon launch. The browser window never even opens, and all I see is the Firefox crash reporter. This problem just started today. Everything was working fine previously.

I have tried opening Firefox in troubleshoot mode, but it still crashes. I've also done two clean reinstalls, deleting all Firefox files in between. This has not helped either.

I've attached a screenshot of the detailed crash report. In case it's relevant, I'm running Windows 11 on a Microsoft Surface laptop with Snapdragon X processor. I know the Snapdragon has had some software compatibility issues, but Firefox had worked fine on it until today. I'm totally stumped, and appreciate any ideas!

The connection was reset

The connection to the server was reset while the page was loading.

   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.

What can I do to resolve this problem.....Problem loading page

So I started using Firefox on my older and newer laptops, but I've noticed that on my older laptop it has started giving me the message "You must log in to this network before you can access the internet", although I am already signed in on my Mozilla account there too. My newer laptop has had no issues for the record. Both systems are running windows 11, both have the same account that I am using, etc. If it makes any difference, my older laptop is using an ethernet cable whilst the newer one is connected via Wi-Fi. When I ran into this issue yesterday on my old laptop, the issue somehow resolved itself after I created a bugzilla account, although I am unsure if this was coicidence, so now I am confused why the issue has showed up again. Awaiting any kind of help or advice, thank you.

i have problem with setting up my proxy. i choose manual proxy configuration, fill the HTTP Proxy & port. When i click ok then input username & password but it keep asking for the username & password. (I have asked the proxy provider they say the proxy is good, no problem)

FF now won't access facebook or amazon websites. FF worked yesterday but wouldn't access either site today. Both Google and MS Edge access both sites. I have cleared cash and reinstalled FF with no luck. Help Please

Firefox 147.0.4 on macOS 26.3 does not work via SOCKS proxy.

Firefox 147.0.4 on Windows 11 x64 works fine via the same intranet SOCKS proxy, with exactly the same settings.

The advantage of Firefox is its flexibility. It supports its own SOCKS proxy settings, independent of systems-wide ones. Unfortunately, it seems this Firefox feature is broken on macOS (but Windows version works perfectly).

Safari 26.3 (21623.2.7.11.6) and DuckDuckGo 1.177.0 (625) web-browsers that use system-wide macOS SOCKS proxy settings also works fine with this intranet proxy server. So it seems SOCKS proxy server itself is OK, and the problem is confined to Firefox on macOS.

Has anyone seen Firefox 147 on macOS work via SOCKS proxy? Is there a principal difference between how Firefox handles SOCKS proxy on macOS vs. Windows? What might be the best way to address the problem on macOS?

Thanks!

I am on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.

(Sorry if the wrong area.)

I'm curious and play with Node-Red a lot.

Just now I am playing with the `http-request` to explore web pages.

I press the `F12` key and the tools pop up and I go through some basic things.

I see/get just about nothing. See pic (Don't know to make it inline.) But the name says it all.

So I've pressed the `F12` key, clicked on the NETWORK and REFRESHED the page.

Now with Chrome.

Whole different set of stuff.

Someone - please. What's going on? I'm not understanding the huge difference with how things are shown.

Hi, since your last update, I can no longer get into my internet provides email on my Windows 11 laptop. It is now saying it's "Not Secure" which of course it is. How can I make it secure? Jenn

I have been an avid user of the Firefox browser on my PC for over a decade but a few days ago, when I tried to access a website on my Firefox browser, it would not connect me to the website. I have many tabs open in my browser and when I try to access any of the tabs, I get the same problem. There's a dot that moves endlessly back and forward in the tab while the screen remains blank. In the heading next to the website address it says "not secure", but it is saying this for all the websites that I was previously able to access and any new website that I enter. How can I fix this to access websites? I have tried restarting my computer but that has not fixed it.
