Firefox connection fails on my mac cleared everything used troubleshooting mode works on windows iphone. I used wireshark and there is no attempt to contact the failing server only see udp broadcast from server. Safari works find DNS is fine cleared everything. Only thing I have not done is reinstall. No trouble connecting to other websites, this is the only one. I ran a virus scan at a loss.

Hi,

I recently noticed an unknown Outlook/Microsoft account (oliveconscious13@outlook.com) saved in my Firefox logins. The email and password appear to be randomly generated, and the account’s preferred language is set to Russian. I have never seen or used this account before.

Here are the key details:

My Firefox account was created on June 8, 2025.

The unknown Microsoft account was created on July 8, 2025.

I only have two devices connected to my Firefox account: my Mac (where the account first appeared) and my Windows PC.

The account is also showing up in Chrome’s saved passwords, which I never intentionally synced with Firefox.

This is a brand-new Mac purchased directly from Apple, so I know it wasn’t a used device.

I’m trying to figure out:

How this account was added to my saved logins.

Whether this was synced from another device.

If there’s any security concern or if my account may be compromised.

Could you check my sync history or logs to see which device added this login, and advise on how to make sure my saved logins are secure?

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...

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?
