Firefox Community Forum

My new Win 11 PC out the box with a Firefox installed on it, worked fine for 2 weeks then an update from you guys causes it to crash, it is stuck in a perpertual reboot loop as windows crash, close then the app restarts despite being told to close, only a reboot will stop it from trying to open and then cause memory leaks.

Also, when are you guys going to incorporate a "Roll back feature" for these situations, so that the older working version can be retrieved.

All my important logins are on firefox and your programmers, whatever they did have jeopardised my ability to access important accounts.

I best check my androind tablet hasn't updates or I will be up the wazoo without a failsafe... Well played Mozilla Devs...

Hi! I've recently found an issue with VirtualBox Extension Pack download in Firefox. Instead of downloading the file, it just shows me a web page with a lot of gibberish, like its trying to display the content of the file itself. I'm using Windows 11 and no extensions in Firefox. The only way i have for the moment to download that file is through Edge. Can you tell me why this happens? Here's the link: https://download.virtualbox.org/virtualbox/7.1.12/Oracle_VirtualBox_Extension_Pack-7.1.12.vbox-extpack Thank you and best regards.

Very often it happens to me that I'm not able to tell whether I'm at the beginning or at the end of a document. The scrollbar colors displayed by Firefox do not provide enough distinctive information to tell. (See images attached.)

From the 80's 'til the 10's we had 3D scrollbars with outset borders giving the impression of a raised scrollbar … for a reason.

Is there a setting to have Firefox display 3D scrollbars on Windows?

How to avoid Firefox restoring previous tabs when starting up. I've read about several solutions (all I could find) that don't work for me. Sometimes I have tens of pages opened and when I close Firefox I don't want 50 pages to be restored. Don't ask me if I have the restore option activated, I haven't. I switched to Nightly to see if it would solve the problem, it did for about 2 months and now it's also happening with Nightly. I have antivirus that include anti-tracking services but I would not know how this could interfere with Firefox settings or if my antivirus has anything to do with it. The issue is so annoying to me that I'm thinking to switch to another browser if I find no solution. I noticed more people complaining about the same issue but it seems not enough for it to be taken seriously in order to solve or be given an explanation. On the other hand it seems not everyone is having the same issue witch makes it even more mind boggling to me. Besides some add-blockers and translation I have no extensions installed. If you happen to know what the issue is I'll be glad to hear from you.

Note:Translation of questions from DEEPL Laptop system version: Windows 10, 21H2, 19044.6093. Firefox version: 141.0.3 (64-bit) The laptop has 16GB of RAM, an AMD 4600H processor, and a GTX 1650 graphics card.

When opening web pages in Firefox (this time it crashed after opening three regular pages), there is a chance it will freeze with a white screen and display a “not responding” pop-up window, while also causing the system audio driver to malfunction. Clicking the speaker icon in the bottom-right corner takes a long time to display the volume slider, but the slider cannot be moved, or adjusting the volume does not produce any sound. Forcing Firefox to close and reopening it also causes it to freeze. The only way to avoid the white screen and unresponsive state is for Firefox to automatically detect the crash and prompt whether to open a new page. The audio driver issue requires restarting the computer to resolve. So what is the underlying issue? How can I report this bug to the official team for analysis and resolution? If it's difficult to resolve, I'll consider switching to the ESR version of Firefox.

(Annoying past experience: This situation has occurred several times before when using Firefox. At that time, I had 2-3 web pages with videos open, mainly video websites, and the speaker icon was directly crossed out with an X, causing the computer desktop to crash as well. The computer became extremely laggy, and the Task Manager and security options were difficult to open. After restarting the computer, Firefox automatically reopened the previously unclosed page, causing the desktop to crash immediately upon startup, entering a loop. It seemed that even Windows Safe Mode didn't work, and a forced upgrade to a major Windows version was required to resolve the issue, followed by reinstalling a bunch of software.)

I found a problem with McAfee Webadvisor 13 Aug 2025 release. It causes flickering in the upper right part of the screen. Disabling it in Extensions fixes the problem. Removing it and reinstalling causes the problem to reoccur. This is new, had no problems yesterday but today all four of my family's computers have this problem. I will report the problem to McAfee and give an update if I get a response.

All of a sudden this evening my title bar is shimmying left to right. If I try to pull down the Bookmarks/History/Downloads box it shimmies, too. I have no idea what caused this to happen and no idea how to fix it. I looked in the Task Manager but I'm not sure anything odd is in there. I ran a scan with McAfee but it didn't pick up anything. I am hoping someone out there can help me with this. I got rid of cache and history. Maybe it's a cookie issue and I should get rid of all of those, too?

I recently bought a new computer, and I'm trying to get everything transferred from my laptop to it. I have a Firefox account, am signed in on both devices, sync is turned on, and passwords are set to sync. I don't know how, but all of my passwords are on my new computer, but not on my laptop and I can't figure out how to get them back. Maybe I messed something up trying to get all of my tabs transferred? It wouldn't be a problem if I was completely done with my laptop, but I'm still going back and forth between the two.

Also, it seems that the passwords on my new computer aren't the most up to date, as I'm signed in to several websites on my laptop, that won't accept the passwords on my new computer.

I would really appreciate any help getting this all straightened out.

I have an older RAID system that I need to login to from a browser. Is there a way to remove the TLS 1.2 protocol for local NAS drives that are only 2 feet away but I can not connect anymore.

When adding an extension, the icon doesnt appear in the tool bar, and is not visible in the customisation menu of the tool bar. It's also impossible to take an extension icon off the tool bar (customisation menu).

Hello, I’m having trouble getting Firefox to work properly on my computer. During installation, the setup process becomes very slow, and once I manage to install it, Firefox hangs or becomes unresponsive within a few seconds after launching.

My system details:

Operating System: Windows 10 64-bit

What I’ve tried so far:

Reinstalling Firefox Running in Safe Mode Clearing profile data Disabling antivirus temporarily

None of these steps solved the problem. There are no specific error messages — the browser just freezes, and I have to close it via Task Manager.

Up until last week, I was able to get pop-up ads in Digg's Adventure. I went into the settings in Firefox and I have the pop-up ads unchecked. It still doesn't allow me to get prizes from ads. Is there something I can do to fix this? Can you help?

Something or somebody emptied my bookmarks. I tried the import/restore routine but was told that Firefox "was unable to process the backup file." I also tried System Restore without success. Can you help me? I don't want to leave Firefox, but the problem reoccurs, which is maddening and time-wasting. Thanks, Bruce Berckman

For the past several days I click on PRINT and it reads PREPARING PREVIEW . it goes on and on and never prints. I get a message from Firefox that says they are repairing some troubles?

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

i keep getting Firefox crashes and i also get Firefox already running close firefox i have the latest version i do not understand why please help thanks

I noticed recently, that you cannot copy and paste with the right click mouse buttons and seems to want me to use the Cntrl C and Cntrl V. Is there some way to re enable that on the mouse? It works in every other application except firefox, and I would prefer to use the mouse, as I am the most comfortable with that.
