As described, firefox is entirely not working for any website. This happened after my computer crashed (hardware problem) and I restarted twice, but could be related to a firefox update that was waiting for me to restart.

Unable to connect

Firefox can’t establish a connection to the server at mesp.finance.gov.bd.

   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.

Does Firefox VPN not work with DNS over HTTPS set to Max Protection, and when using a custom provider?

With the VPN on and DNS over HTTPS set to Max Protection set to custom provider, no pages will load and I get an error screen/can't connect to proxy screen.

Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

I own the domain name sabbathcalendar.com which is redirected to my website at sabbathcalendar.org. Firefox consistently gives the following message:

"Hmm. We’re having trouble finding that site. We can’t connect to the server at www.sabbathcalendar.com."

It doesn't matter how I enter the URL. When I simply enter "sabbathcalendar.com" in either Brave or Microsoft Edge, both browsers will immediately connect to my website at sabbathcalendar.org with no problem.

I asked a question last night about whether or not Firefox had an IP Address. Sounded silly, but I was dealing with an unfamiliar IP. I did eventually find apps that locate IP Addresses. Problem solved . Just want to thank James for taking the time to respond to my question.

I travel to two different locations a few times a year. I use the same basic "computer" for each one, though they're far apart. It works through a "sneaker network," where data files, profiles, etc, are copied to a portable hard drive and then copied to the next computer, so they're fairly identical.

The problem is that this last time (and I've been doing this for perhaps about 3 years), Firefox has refused to do anything online. I can use it offline, but not online. The "work online" is unchecked, so it should be online. But it refuses to do anything.

After several Firefox reboots, windows reboots, checking everything, Firefox still does nothing.

Currently I'm using Waterfox and Edge. Both work fine. Thunderbird works fine.

I've had this problem since Tuesday night. So about 48 hours now, and nothing at all.

The way I transfer from one computer to another without losing email or current Firefox status is to copy the newest profile over, delete the old, and then copy the current program, as well.

Thus, the program is up to date, as is the profile, but all I get when I type in any address is that dot thing at the top, going side to side.

Thank you in advance.

Current Behavior When Firefox is set to offline mode (File → Work Offline), the Developer Tools Network tab does not display request body of requests that web applications attempt to make. This creates a significant gap in debugging capabilities, as developers cannot inspect request payloads details that would normally be visible.

Requested Enhancement Enable the Network tab to capture and display attempted network requests payload even when offline mode is enabled

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!
