NOTE: I have marked this as "Solved" because I figured out the problem described below, and I fixed it. See my following message here for a description of my solution.

Original message starts here ...

I'm using Firefox 144.0 under Debian Linux. I've used Firefox on this machine for years with no problem. Firefox can easily connect to literally thousands of web servers on the internet, both via HTTP and HTTPS.

But now, I'm having an issue:

I started running a web server on the same machine that Firefox is running on. This server only listens for non-HTTPS connections on port 80. I am not using any proxy server with Firefox.

I can easily and directly connect to my local web server's pages from my local machine from Chrome, w3m, curl, and direct telnet connections to port 80 ... all of which are addressing the publicly accessible domain name for my local web server. However, However, Firefox refuses to connect to any URL's on my local machine, and it gives me the following explanation:

Unable to connect

Firefox can’t establish a connection to the server at [ my server's domain name ].

   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.

In Firefox, I have all auto-forcing of HTTPS disabled by means of Don’t enable HTTPS-Only Mode turned on.

I get the same error in Firefox whether I connect via a URL like "http://MYFULLDOMAINNAME" or a URL like "http://AAA.BBB.CCC.DDD", where "AAA.BBB.CCC.DDD" is my machine's publicly accessible static IP address and "MYFULLDOMAINNAME" is the long-standing, publicly accessible domain name for my machine ... both with and without a suffix of ":80" on the supplied URL.

And again, all other browsers on my machine have no problem whatsoever connecting to my own local web server on this same local machine of mine using those same URL's.

And all browsers (Firefox and otherwise) that are running on other machines all over the internet have no problem connecting to that same web server via the same URL's that I described above

Also, I have no firewall rules on my machine which would block access to my own machine's port 80.

What could be causing this error in Firefox, and what might I be able to do to fix it?

Thank you very much in advance.

UPDATE: Just a bit more information. Looking at the web logs, I see that Firefox's request never even reaches my local web server. In other words, Firefox itself is not even trying to make a TCPIP port 80 connection to my local web server in the first place

Each time I click a particular icon, it goes to a page to set up an account for that website. But I already have an account there. How can I change the icon to go to my account instead of the setup page?

after entering information clicking the save button does nothing, however etnering the card information the format it displays the data is xxxx xxxxxxxxxxxx rather than what you would expect xxxx xxxx xxxx xxxx

I created a firefox profile from another, so I start with the same saved passwords and bookmarks which is nice.

Now I want to sync this new profile with the sync service of the mozilla account.

First, I tried to use the same mozilla account I was using for the original profile (which would be ideal), but I get an error saying: This account is already in use.

OK, so I thought, instead, I could use an alternative mozilla account to sync this new copied profile, but, when I try to register/login with another account I get this other error:

This profile was previously synced with a different account.

To keep your data organized and secure, each Firefox profile can only be synced with one account. To log in using ***@***, you must create a new profile.

Isn't there anyway to sync this new profile to a mozilla account? What's the whole point of copying profiles if you, after, cannot sync it? :/

Hi,

Using the new profile manager, is there a way to launch Firefox using a specific profile?

I like the new Profile manager feature! As I understand it, it is completely separate from the old way of managing profiles with "firefox -p" and about::profiles. One feature of the old system that I really liked was the ability to launch Firefox with a specific profile. I was using this to create separate shortcuts to launch my Personal profile or my Work one. Is this possible with the new profile management system? I know that there is an option to select a default profile - but this is not as useful as that means that the same profile would always be used.

Thanks!

Can someone help please: - I've been trying to buy some tickets for an event in France. When I access the following from Firefox (140.6.0esr (64-bit)) on Debian GNU/Linux 13 (trixie)) the ticketing purchase options don't show. When I access it from Chrome on Android or Edge on Windows it does show. https://www.circuitdesremparts.com/prochaine-edition/billetterie/ It seems I've now missed any Tribune tickets.

Thanks, Tim

When trying to enter a full screen mode pressing modkey + f or F11 buttons my screen is cut in the upper part. The resolution of my pc is 1600x900 however my browser, after entering into a full screen mode, turns the resolution in 1600x917 and I do not understand why it automatically assigns this resolution. I have tried turning off the fingerprint option but it did not help. My os is x64 linuxm distro is the arch linux, and I use the awesome window manager. I tried using the Librewolf and I had the same problem when entering the full screen mode. I've set the linux recently so I guess I have no settings that could have potentially be the cause of the problem.

In Firefox, I have audio and video autoplay blocked globally, and added an exception for one particular website (Discord). However, Discord now only autoplays videos once, but doesn't loop them as it should (they implemented GIFs as videos, but now they don't loop).

Of course this could be interpreted as a bug in Discord's web client. However, there shouldn't be a difference between a website that got an exception and autoplay being globally allowed. Therefore i suspect that there is a bug in firefox where some property, state, or hint is set differently depending on whether a page has been added to exceptions or autoplay is allowed globally.

Is there anything i can do to work around this? I really want an autoplay exception to actually work as expected (the website doesn't need to know that it's special)

OS: Linux Recently, firefox has been annoying me with not closing a tab when I click the X like normal. I have to right click and close it, or press ctrl w. I am unable to move tabs around, as well. I am not sure since when this next bit has been happening, but I am also unable to interact with many elements of the top bar. The only thing of the firefox ui besides the websites themselves that let me interact with them at the moment is the home button, the new tab button, bookmarked sites, and that box icon on the left corner that lets you look at previously closed tabs. My Firefox's version should around, I believe it is 140.5.0 ESR. Thank you in advance. Update: Upon a restart of firefox, it appears to be working again as normal.. However, the bit with tabs not closing when the X is clicked and not being able to move tabs around has been happening multiple previous times, and it may come back. Update again: The issue does come back after some usage. I'm using KDE plasma with Wayland. I will try what the answer asked, and come back later. Update: This seems to happen very randomly and is not reproducible for me.. It will go a few days being fine, then randomly freeze again. Has not happened under another user, at least not yet.

When searching from the search bar how do I make it to where YouTube doesn't come up as an option for when I'm looking for a video? How do I block YouTube from my search

Why isn't the Firefox browser supported by many services and social networks? They even state in the warning that Firefox is not supported! Why should users tolerate this?

Почему браузер FireFox не поддерживается многими сервисами и социальными сетями? Так и пишут в предупреждение, что этот браузер FireFox не поддерживается! Почему пользователи должны терпеть это?

I expected "export passwords" to also export the password to my mozilla account, but it did not. I'm now locked out of my account. I signed into this form with google, is there something similar I can do to get my mozilla account back? The drive I had firefox on is wiped.
