Firefox 社群討論區

When I go to (seemingly) any Elsevier site, the browser tab immediately closes with no error or explanation. An example is this site:

https://www.sciencedirect.com/science/article/pii/0167508784900164

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

My search history is clogged with repetitions of the same search. For example I log onto my bank account and the search history shows 15 plus or minus entries. It also happens with other sites i visit often. I searched the internet about "history" and It was suggested that is check extensions and remove them. Then Just today my bank sign-in icon was gone. Sorry Im not always using the correct terminolgy.

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?

On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

When I click on the URL bar, the entire URL is highlighted. Then, if I click the left arrow, it brings my cursor to the start of the URL. After it moves my cursor, it then prepends the URL with the protocol (https://, http://, etc). My cursor is now no longer on the left side, and I need to hit my left-arrow key several more times to reach the left side.

Here is a screen recording of the issue: https://youtu.be/JtoL88bqSB0

Ideally, it would bring my cursor to the left side of the protocol, or show the entire URL, with protocol, in the URL bar, so that it does not need to prepend it.

I talk to friends on facebook/messenger. Previously my conversations were always on Firefox. But suddenly a couple of months ago I could no longer use my camera and my microphone on Firefox, and had to install a new browser. I have been trying several times to give Firefox permission to use my camera and my microphone, but sofar without success. What do I have to do?

I run a mac mini with OS X Catalina. I keep to that operating system as a number of my work apps work better. I am on the latest version of Firefox (64 bit) 144.0

In the last couple of years I have found webforms on Firefox seem to omit links or progress buttons like CONTINUE. When I check with the issuer or my colleagues I find they all use CHROME.

I have wasted a great deal of time on what I would have thought is a Minimum requirement issue.

Please give me one reason why I should stay with Firefox and not change to Chrome

thank you

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.
