Firefox Community Forum

7/7/2026 Last night Firefox on my laptop performed an automatic update to the latest Firefox version. The new Firefox has a very bad setting in about;config .. this new Firefox can only show 1 tab ... it is opening up a new tab on top of the first tab, making it impossible to have more than 1 tab ..

This is going cause problems for thousands of Firefox users .. . how I fix this problem ... I tried setting the add tab settings into about;config to add a new tab to the right of the current tab, but my change made no difference ... how can I fix this problem ... does Firefox have a plan on how to fix for this problem for thousands of Firefox users.. this problem will impact thousands of Firefox users..

I just can't believe after 25 years of using Firefox I have to change to Microsoft browsers. Every website I have an issue with says it's Firefox and their solution is to use Chrome or Edge. Why are you so stupid to allow this happen without an easy fix and no online help to keep longtime loyal users???

You are forcing me to go to the competition for the rest of my life, does that not resonate with anyone there???

I find that my desktop browser firefox is very slow or doesn't work at all on a lot of websites like amazon or fortnine.

My internet connection and computer are not the issue: 270Mbps (wired connection) Processor AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz) Installed RAM 32.0 GB (31.1 GB usable) Graphics card NVIDIA GeForce RTX 4070 Ti SUPER (16 GB) Storage 3.58 TB of 10.92 TB used System type 64-bit operating system, x64-based processor (Windows 11)

My old PC and my mobile phone runs these website fine.

Sometimes the website will work for a moment, but stop and just load for ever after I open a new tab or clink a link. My task manager doesn't show any ethernet usage despite the tabs indicating they are trying to load. Refreshing the tabs does nothing and no matter how long I leave them they don't load. All my drivers, OS and programs are up to date. I have disabled my enhanced tracking protection and I don't have any adblockers. I have tried using the CMD "ipconfig -renew" and using ccleaner to clear out my cookies and cache but, nothing seems to have any lasting effect.

I am losing my mind trying to fix this. Why can I not browse the internet on my PC?

Any help on this would be amazing and much appreciated.

Sincerely, Calvin

I'm experiencing an intermittent issue with Firefox and I'm trying to figure out what might be causing it.

Occasionally, Firefox stops loading pages in new tabs. If I open a new tab and try to navigate to any website, it won't load, it'll state "waiting for www.[anywebsite].com" forever. However, if I use a tab that was already open before the issue started, I can still navigate to different websites from that tab without any problems.

The only reliable fix I've found is to completely close Firefox and start it again.

One strange thing I've noticed is that, sometimes while this issue is happening, if I put my laptop to sleep and then wake it up again, Firefox starts working normally, including in new tabs, without needing to restart the browser. But this isn't a something that works everytime.

I've already gone through the troubleshooting steps in the Mozilla Support article "Firefox can't load websites but other browsers can", but none of the suggested solutions resolved the issue.

I also tried disabling all my extensions, one by one, but the problem still occurs.

Has anyone seen this behavior before or knows what could cause it?

Additional information:

Firefox version: 152.0.2 (64-bit) (currently shows an available update requiring a restart, but it never seems to update even when enforced restarting) Operating system: Windows 1p Pro Version 10.0.18363 Build 18363

I'd appreciate any answers

My Firefox browser (nightly snap 154.0a1 on Ubuntu 24.04) has been misbehaving lately (~2 weeks now) and I'm at a loss why.

First, when I scroll using the mouse wheel, the scrollbar continuously shoots back to the top constantly during scrolling.

Second, when I type text in a Google box and hit enter key, it drops to the next line - like one would expect in a text processing application.

Third, when on YouTube, trying to rewind/forward video instead starts navigating to clickable links. Of particular note (see the attached screenshots) is the appearance of text (such as "Skip navigation" and "Volume" to name a few) - something I've never seen before.

This happens with a new profile as well.

Now, I know that nightly will sometimes have broken items but this is a weird one. I at one time thought the batteries on my wireless keyboard could be responsible but new batteries (confirmed new with a digital multimeter) did not change that.

I'm on Ubuntu 24.04 LTS fully patched. Anyone here with ideas on what it might be?

I am trying to migrate from a windows 10 computer to a Windows 11 computer. I have installed Firefox on the new computer. I exported my bookmarks from the windows 10 computer to a HTML file. I then imported them to the Windows 11 computer. I thought the import hadn't worked but finally found them Bookmarks Menu folder under Other Bookmarks. When I tried to move them to the Other Bookmarks folder Firefox wouldn't allow it. I finally went to the Other Bookmarks folder in Bookmarks Menu and selected all the files there, and copied them to the clipboard. Since the Other Bookmarks folder was no longer available in the left column, I closed Library and opened a new Library. I then pasted the files I had stored into Other Bookmarks. That seemed to work. However, when I click Other Bookmarks in the upper right hand corner of Firefox all the files there have the wire frame globe for icons and don't work. If I go to the Other Bookmarks folder in Bookmarks, those bookmarks still work. The bookmarks aren't of much use if I can't access them from Firefox. I am writing this on my Windows 10 computer but both computers have the same version of Firefox.

Hi, I had to reinstall my windows where I thought my Firefox would sync up upon reinstallation. However, nothing would sync up and the best I could do myself was to import pretty out-of-date Chrome data. When I to my firefox account and scroll to connected services I see my last PC name with its firefox login. Is there any way to recover that data and import to my current device? I read you kept sync data as encrypted data on your Mozilla servers, so I hope that's a viable solution.

Hi there! My payment methods are stored on Firefox and do come up once a box for credit card number appears on any site. However, I have only the option to add a new card but not to view or edit? Why? Please see attached screenshots. Please help - thank you.

Last night Firefox on my laptop performed an automatic Firefox update.. The Firefox that was installed can only display a single tab. This is a major for me, since I normally work with multiple tabs. This problem may impact a large number of Firefox users. The documented recommended fix for this problem did not fix the problem.

I terminated my McAfee subscription, as Windows 11 and Microsoft Office 360 have Microsoft Defender included. I keep getting Mozilla Firefox warning notices saying my McAfee licence has expired, Trojan Virus found on hard drive, multiple virus on my computer, Critical errors etc. I have had MS Defender do several scans and no problems have been detected. Can you help correct this or do I have a virus that Defender cant detect? I have tried to copy one of the notices but it comes up as a link to further notices and I am concerned it is another virus. The notices are all Mozilla badged with suggestions such as Scan and fix, Turn on protection, Update windows and more. I am able to delete them, but after a few minutes they return. Regards Robert.

The Back arrow/button in the address bar is unclickable, greyed out and no longer functional.

Is there a specific fix we can make in about:config to regain function of the back arrow/button? A response from a person (or people) would be appreciated.

Your really do not want as much detail from me as possible. I guarantee that. ("Everything is connected" should be enough of an explanation.) But you ask for details . . . .

This is specifically about updates (not also installation). Which update and and when I do not know, although it could be Microsoft fooling around with Firefox functionality. OR it could be ESR being updated when updates have been disabled. So that raises the question about the extent to which Microsoft is also configuring Firefox when FF is the default browser. (We deserve to know.) I have changed back to normal updates, and will try to disable the incessant frequent updates which always include undoing new standardized FF configurations that were labor intensive to find fixes for the first time. Fortunately, I have kept a file of many of them. Apparently A.I. (oops, maybe it was Firefox) has agreed to give access to Microsoft to interfere with how Firefox is configured when Firefox is the default browser, regardless of the FF version,

Specific details (I will try to make this as repetitive, overly simplified, and superfluous as the auto a.i. responses though I most likely will fail): And if expressing dissatisfaction is violating the rules and guidelines, then please understand I am human, and do not like everything I do online being the result of 1/0 on/off/humanizing A.I. (including genetically . . . oh yeah, we all know where this free "training" of a.i. is going that we are all being used to do without our consent - and worse).

The back arrow/button on the address bar is no longer clickable and it is greyed out. It is apparently another new Firefox standardization that is not one size fits all. The easy solution would have been for the people who do not like the feature to be advised to remove the button/arrow from the address bar. But, no. Instead, at some point, a new update standardized the arrow/button to become unclickable and dysfunctional.

I found a question about how to make the back arrow/button functional again. The question was not why has it been made dysfunctional. The answer was why it had been made dysfunctional.

In short, some people found the arrow/button to be problematic. A.I. said people were losing information they had input to a form, when they used the back arrow/button before completing the form.

So what did FF (or A.I.?) do? Made the arrow/button dysfunctional for everyone because a few folks in lala land did use common sense, and simply remove the button from the address bar so they would not be tempted to use it and lose information.

Why was that a solution instead of Support (A.I.?) telling people who found the arrow/button to be problematic, to remove the arrow/button from the address bar? Really? Why not advise people to make the feature dysfunctional for themselves - instead of the solution being to make it dysfunctional for everyone who uses Firefox Browser.

Here is the basic, simple, question and content I would have preferred, and I'm guessing many actual people would have too.:

Again:

The Back arrow/button in the address bar is unclickable, greyed out and no longer functional. Is there a specific fix we can make in about:config to regain function of the back arrow/button? A response from a person (or people) would be appreciated.

Thanks in advance.

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?
