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...

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

Dear Firefox Support, My issue is with the browser I use 136.0.1 (64-bit). Select Help menu (Restart to update Firefox) I've preformed this task several times so far and I keep getting the something over as I click on Help menu. I restart the browser again however it is the same thing "Restart" again. What is my next step here?

Thank you, Dave 18 March 2025

I wanted to try the new split screen feature. The guide says you need the latest version 149. When I check 'About Firefox' it says I have version 140.9 but it also says 'Firefox up-to-date'. Could you advise how I can update to latest version 149 please?

After the last update on my desktop browser, my password was requested in order to "install a new helper tool." But it isn't accepting my password, even after I double checked what it was. And there's no Change Password link.

Since I can still access the Firefox browser on my iPhone, I thought of I'd change my password there and sync, but the new password isn't accepted either. Once a password isn't accepted, pressing cancel closes the app and it can't be reopened without a Force Quit first.

And 'round and 'round I go. How do I regain access to my desktop browser?

Thanks.

I use Firefox on a ASUS Vivobook running Windows 11. On April 1, it tried to update to version 137.0, but failed and led me into a update loop of sorts. I had to re-install Firefox just to force an update on it, and that worked for a bit. Just today, it decided to update... and led me into ANOTHER update loop, and it's saying that the "install failed" when I check the update history.

Is anybody else experiencing this bug, and is there a way to fix it?

Greetings, Team. When Firefox does an Auto-update while starting, an error message arrives, " NSIS Error:

Error writing temporary file. Make sure your temp folder is valid.

OK " Please, where and what name does this 'temp folder' have?

How may I fix this Error?

Thank y'all in advance. Phil T. ps W10, Chkdsk OK, system appears OK.

How should I fix the frozen browser. Firefox updated ok from another user account on this computer, though Firefox has always updated for all accounts on the computer when updated from any of the accounts. The installer tool got caught in a loop to install until it froze the browser on the third retry. What should I do?

While I'm using Firefox, I try to go to a new website and Firefox says that it's installing a new version and I need to stop what I'm doing and restart. When Firefox restarts, it forces me to create a new profile and I've lost everything I had before.

This happens two or three times a day.

I have been getting asked to update my firefox for the past 2 weeks now. Everytime, it asks me to update my firefox. I update it, and then when I quit firefox (restart computer) and re enter, it asks me to enter my admin details to be able to install a helper tool to finish installation.

Attached is a video of that happening. Essentially, I have downloaded the latest version directly off of mozilla website, but it continously asks me to update & install helper tool.

When credentials are entered, it doesn't do anything. When I press cancel, the application does not respond and need to force quit. Either way, I cannot access firefox everytime it asks me for an update.

Any help would be appreciated.

For about the last 2 months, when I either get a notification that an update is available or I manually check for updates, both Firefox and Thunderbird are stuck in "Downloading updates -- 0 bytes" on 2 Windows 11 computers. Eventually, like a half an hour to an hour later, the update downloads and I can install the update. This has been going on for 2 months now. As a 20 plus year user of Mozilla and also a long-time financial contributor, this problem going on for 2 months is getting old. And yes, I have checked my antivirus and firewall. Is Mozilla aware of the problem and is there a solution?

My version of Firefox is 108.0.1 -- I am running Windows 10 on a machine that Windows says is not capable of running Windows 11

My installation of Firefox resides on my D: drive. It uses quite a bit of space for cache and other things on my C: drive but it starts and runs on my D: drive.Now I am forced to update, but I can't get the installer to recognize an installation on the D: drive and update it. Instead it makes a new installation on my C: drive and I lose my appearance customizations, history and bookmarks.

I have never believed and cannot accept that an application absolutely MUST reside on the C: drive. It's lazy programming (something I used to do for a living). I can't believe Mozilla programmers wrote an installer that insists that Firefox must live there, so what am I missing? How do I tell the installer to find and update my existing application?

Thanks for your help. I feel as if I am missing something that ought to be obvious.

HERE'S HOW I SOLVED THIS "SECURE CONNECTION FAILED" ISSUE:

Kept getting this error when attempting to update Firefox; didn't matter which browser I used; went through the forum postings and tried every this-and-that-and-this-and-that posted there; didn't work; finally --

i opened a $10.00 30-day hotspot account with Xfinity, and the download worked perfectly.

PROBLEM SOLVED.

On my wifes PC Firefox appears to be doing random things. First the screen turned pink, then the taskbar icon has a gear-wheel overlaying it, and she is unable to do anything, like logging into zoom. Google searches work but clicking on any link goes nowhere and just sits. Is there a way of returning to it's previous boring but appreciated habit of just working, without uninstalling and re-installing from scratch please? thanks (she is currently using our fallback laptop in her office so I can't access her pc for an hour or so.)

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

I received a msg from Mozilla that my Firefox was out of date and to download current version. I downloaded the current version but it does not update. I went to the menue and firefox help and it said automatic downloads disabled by system adminiestrator, I'm running linux mint. How do I get the download to update?
