Firefox Community Forum

Good Morning, I have been trying to access Whatsapp web through the Mozilla browser but i have been unable now for the last four weeks. When i use other browsers then i am able to access the internet. Thank you.

Regards, Gitonga

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

Was prompted to download a program to Firefox before I paid my phone bill. I did not recognize the web address or name that was shown, and the account number from which recent payment was deducted did match any accounts I hold or held in the past. I cancelled the action immediately, without downloading, but am still concerned. I found nothing on the internet about this, just got a summation chat AI response that stated the phone company had no download/extension for Firefox. Has anyone had any experience like this or could someone shed some light on this?

i need to access my aol and yahoo email like i was always able to do using firefox. now it states security risk and "nothing " you can do? please advise . i need access to my desktop to easliy see my emails and don't like using my phone

I am trying to pull up the list of the subscriptions and auto payments I have on Paypal. All the other pages on the site display correctly. Microsoft Edge displays the page correctly.

I have attached two screenshots, the first is how Firefox shows it. the second is the correct display using Microsoft Edge.

Note the correct page shows a lot of offers on the right side with the list of payments icons on the left in proper form. The incorrect screenshot does not show the right side offer material at all . The layout of the text and icons are nothing like they should be.

Changing the magnification does not help as my other Paypal pages are affected and the result is just a smaller version of the incorrect page with the icons still offset and is not usable for it's intended purpose.. Also the text is to small to read.

When I first try to open the page it flashes momentarily on the correct view, then immediately goes to the bad view. Is it possible there is some "locking" factor missing when I get the flash display?

This started within the last 6 months. I suspect something about the page is not on the same criteria as Firefox. If no one else has seen this then I must have something inconsistent with that page.

When I do this:

Click the menu button Fx89menuButton to open the menu panel. Click Bookmarks and then click the Manage bookmarks bar at the bottom. In the Library window, click the Import and Backup button and then select Restore.

I get a blank slate. No files listed.

When I go into the Profile, I see C:\Users\whatt\AppData\Roaming\Mozilla\Firefox\Profiles\shgdgxn6.default-release-1752271533405\bookmarkbackups

How do I restore bookmarks from that file?

Is there any way I can prevent Mozilla from installing/enabling more AI features on my Firefox browser in the future?

I do not want AI running on my machine. I do not want AI integration in my browser. I understand I will still run into AI in the wilds of the internet, but I especially do not want these features enabled ON MY OWN MACHINE in an update without me specifically opting into them. Installing and enabling this without user opt-in communicates clear disrespect to the users.

I did a cursory search here for similar questions and Mozilla staff appear to be stating there will be no AI in Firefox unless the user specifically enables it, and it is as simple as disabling them via settings if "accidentally" enabled. This was not my experience, and it is alarming to see false information provided to users .

I have found other sources indicating the following must be set to false in about:config in order to disable browser-side AI/AI integration: browser.ml.chat.enabled browser.ml.chat.page.footerBadge browser.ml.chat.page.menuBadge browser.ml.chat.shortcuts browser.ml.chat.shortcuts.custom browser.ml.chat.sidebar browser.ml.checkForMemory browser.ml.enable browser.ml.linkPreview.shift

Is that all of them, will these disable ALL of the AI in Firefox?

Are there any other settings I need to set to false to ensure no AI is either running on my machine or the browser is not integrating AI functionality from third parties?

Is there any way to ensure Mozilla doesn't force AI features to be enabled without my say-so (again)?

Are there any privacy-minded browsers comparable to Firefox that DO respect their users with regards to forcing AI on them? It may be time to jump ship.

This wave of so-called AI (really nothing of the sort) is a nightmare for security, usability, performance and efficiency and if you keep forcing it on us I'll be jumping ship, probably for whichever fork excising it all gets popular.

I've been using first the Mozilla suite and then Firefox (since it was called Firebird, even) for twenty years now, don't do this to the browser I love.

Since the new CEO of Firefox seems to be very determined to add more AI features to the browser that I've been using (among other things) specifically to escape AI slop, I will be considering switching to another browser. It will be disheartening to abandon the browser I've been using for years, but I value my personal data (and cpu) too much to let an AI handle it. I appreciated his words that it would be "Completely opt-in, you have full control, and if you try it and find it’s not for you, you can choose to switch it off", but I strongly believe that all AI browsers are inherently insecure. The first AI feature that I can't make completely disappear forever with one click will be my sign to switch browsers. Hopefully, Firefox re-thinks its approach and decides not to destroy the exact thing that makes it so valuable - the commitment to protect the users' privacy.

I have an Investors.com account and a feature they offer is a stock sector data table that shows recent performance and other information. When I try to open these tables they close immediately, but if I use my tablet with a different browser they will remain open. I believe this is a simple setting that I need to adjust, but I don't know enough to figure it out.

Hi, I noticed that my Firefox version has just been force-updated, on two of my computers, even though I had the automated updates unselected. I also noticed that the new version had added an opt-out option to use "AI" for my tabs which I do not want. There may be other settings that have appeared like this forcing "AI" on me and I am not going to check all of them. I will uninstall Firefox as it is no longer respecting my privacy and autonomy as a user, following the full-blown embrace of "genAI" which goes completely opposite Firefox values such as privacy, ethics, environmental responsibility and respect of their users. I might come back when Firefox goes back to being a privacy and environmentally-friendly browser.

I installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.

On this page https://www.apc.org/en/project/member-engagement-and-travel-fund the first section of text is missed out from reader view - so that the text starts half way through the article. I understand the table will be ignored - and the internal table of contents links at the very top, but there is a paragraph in between those things that is being ignored entirely. The normal text parts should all be included for the article to make sense.

I have tried changing the markup so the paragraph was not inside the same div as the table or table of contents but this does not seem to make any difference.

Google chrome reader view handles the page fine.

Any tips no how to change markup to avoid this or is there a way to fix it?
