Firefox Community Forum

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.

Chrome resolves local DNS just fine.

Firefox fails: Unable to connect Firefox can’t connect to the server a

I have DNS over https disabled already and have troubleshooted various other settings.

Does the latest Firefox version have an IP Address? Possibly 150.1.2?

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

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?

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.

Firefox is not browsing on my laptop...to be fair neither is Microsoft edge so I'm not blaming Firefox but it's happened during the day totally out of the blue. I am linked to the internet but no pages will load. The firewall says Firefox is allowed through. I can't run troubleshooting because I can't link to the internet! Very annoying.

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.

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.

Without any change made on my part, effective May 18, have been denied access to the web. This even includes long time bookmarked important investing/banking, etc. Have checked macOS Privacy & Security settings but not aware of any blocking there. Has recent Firefox update changed things? I have not updated Firefox updates for some time.

Why can't I open?

This is what I get: Server Not Found

Firefox can’t connect to the server at water.weather.gov What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.
