Firefox Community Forum

It's completely hopeless to get out at the Internet with Firefox, but no problems with my Macs own Safari. I have tried to add Firefox to the firewall as said in the Help-section, but i dosn't work. I am not good at computers. I have three Macs: One Mini with Tahoe 26.5.1; an old MacBook Pro with Catalina 10.15.7 and a MacBook Pro with Sonoma 8.14.3. I use a router connected via fiber.

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?

I regularly and repeatedly get errors messages similar to the one below:

   Server Not Found

   Firefox can’t connect to the server at www.filepuma.com

   'What can you do about it?

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

I can find no way to correct this. Can you help?

It was working just fine, and suddenly it stopped working. I hadn't rebooted my computer for over a month, and accidentally popped the circuit breaker the computer was connected to, so it rebooted for the first time in a long time. No other issues except Firefox will not connect to the internet when Proton VPN is running, but Firefox works just fine when the VPN is turned off.

I updated to the latest version of Firefox, so I assume that's the same thing as reinstalling it.

Proton VPN allows you to do what they call "split tunneling", where some browsers are excluded from the VPN (Firefox) and other browsers are always behind the VPN (everything else). I use Firefox as a secondary backup browser when the VPN is a problem and I don't want to turn it off.

I ran the Firefox "Safe Mode" and that failed to connect as well. I don't think it's the VPN? But maybe?

Any help appreciated, and thanks in advance.

While I tried to connect to the web page "http://eprison.nic.in/npip/public/MyVisitRegistration", I found a reply saying "Firefox can’t connect to the server at eprison.nic.in". Thus, is there any way that I can possibly connect to the web page because I want to pay a VC visit from a distance to my son arrested in Mumbai Central Prison.

I use the Firefox browser for MacOS and i use and XBOX series X controller. I connect via Mac Bluetooth and use my XBOX controller for many browser gaming platforms such as XBOX Cloud. The Firefox browser always has connection issues. The controller works perfectly with many other browsers such as Chrome, Edge, DuckDuckGo, Opera (all iterations). Firefox is the only browser were I've had connection issues.

When I try to open any internet site, I get the Fox icon with cable, saying it can not Access.I did check updates, last on list was June 26,2026. Did Firefox know this with the false window there? How do I get my account on my Dell computer recovered? I am on my PC11 tablet now. Mary Rogers

Firefox can’t connect to the server I am not a tech person says simple jargon will be, appreciated thank you.

I had a proxy set manually before and it was working just well, after I updated firefox it stopped asking for username password for my proxy and I keep getting no network error on every website I check. I also reentered the proxy data again and checked somethings in the about:config page to be true but still doesn't work.
