I noticed that firefox stays in memory after I close it. In fact, If I open and close firefox 10 times, ten processes are shown in memory, each consuming around 100Mb.

I'm using Windows 7 in my corporate computer and I have been using Firefox 65.0.1 x64. I've tried to use it in safe mode (no add-ons) and problem persisted. I uninstalled it, deleted all Mozilla data in AppData and ProgramData and reinstalled it fresh. The problem persisted.

Then I installed the 32-bit version of Firefox and the problem is no more. Is it a bug that has to be fixed or some setting that shoudn't be enabled?

Thank you.

Hi all. Seems like after updates, my computer slows down. It has become so recognizable, I know when the registry errors appear, as my computer performance falls off. I must use Reginout Registry cleaner, and CC Cleaner to restore performance. Along with any FireFox updates, my bookmarks have all been deleted many times over. I no longer attempt to re-install, as they continually get deleted, and so simple fix is available to me that I can understand. Thank you.

We are currently having to role back to FireFox ESR 52.9 from the latest Quantum build of FireFox 60.3.0. Due to the fact that this version utilizes WebGl 2. Our older systems will not render one of the educational games we utilize in the our School District any longer due to the fact that Quantum uses WebGl 2 instead WebGl 1. We have tested and verified that ESR 52.9 renders the game properly.

I have been trying to disable the automatic update in utilizing the user.js file and the cfg file. The computers are apart of the domain. From what I have read only new user profiles will get the new user.js settings while all existing profiles will retain the old settings so we plan on reimaging these computers so all existing profiles will be wiped.

I have also seen users block the updates by changing the Host File which we will not do. Some sites state create a profile folder in the defaults folder other show place the user.js file in the pref folder. So I am lost at this point. I have followed this guide as well:

https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Enterprise_deployment_before_60#Changes_Over_Time

I have placed the 00_admin-prefs.js with the exact settings shown and have the mozilla.cfg file in the same folder as the js. both are in the defaults\pref

When trying to run FireFox I am am not getting:

Failed to read the configuration file. Please contact your Administrator. (I am the Admin). My domain creds give me admin privileges on all computers.

I know this folder also holds the channel-pref.js so I am not sure if I can add what I need to that file.

If someone would please help me determine what is going on. Why wont firefox copy the either a user.js file or utilize the cfg file I created to each new profile that gets created when logging into the computer.

Ever since Firefox nightly did an update a few days ago, I have been unable to run it from the normal shortcut. I had to make a copy of the exe and rename it and only then would it work from the renamed file. If I click a link in Thunderbird, for example it still looks for Firefox.exe and not the renamed file. If I change the tile to Firefox.exe.bak so that only Firefox1.exe is accessible, I still have to run it manually from that new file name rather than the default. This is a new install of Windows 7 x64 Ultimate and this is the only time I have ever had problems with nightly. Now, when I restart the browser, it downloads a new firefox.exe and the error returns. I would rather try and fix the problem than remove all traces of it then reinstall, that would be like ignoring the problem and starting over which won't 'fix' the error that others might have.

Under Wndows XP, Firefox will no longer start, and won't reinstall or install

I had been running the latest version (52.8) of Firefox supported under Windows XP, but now I can no longer run Firefox, and, worse, cannot reinstall it.


On June 7, Firefox lost all the tabs from the previous day. This happens from time to time, and it's simplest first to try restoring Windows to the previous checkpoint: this is sometimes successful in that Firefox then does display tabs. I restored Windows to the then most recent checkpoint, June 6, only to find the attempted cure worse than the disease: Firefox would not even start. There were no messages of any type.

Attempts either to create a new Firefox profile (-p) or to start Firefox in safe mode (Shift) were no different. Windows Task Manager showed no evidence, however transient, of either any Application or Process for Firefox. Again, there were no messages of any type.

Restoring Windows to still earlier dates produced the same situation: Firefox would not run, exactly as after the initial restoration.

Deleting the (only) Firefox profile made no difference.


All subsequent attempts to reinstall Firefox--whether or not Firefox had been uninstalled--have been equally unsuccessful, and equally mute.

Program Firefox Installer.exe (306 KB in size, downloaded from https://stubdowloader.cdn.mozilla.net, for example) begins a process which occupies either 2,484KB or 2,488KB of storage, but which does nothing. I tried several Firefox installers (all downloaded via various links from Mozilla): all are bit-for-bit identical, albeit with one occasional exception, i.e., sometimes a string is "duckduckgo.", and sometimes it's "getfirefox-". None of these installers produces any message, and each creates a process which occupies c. 2.5MB and then does nothing.

Knowing that it would not run successfully under Windows XP, I nonetheless tried later Firefox installers (e.g., Firefox Setup 60.0.2.exe downloaded from https://download-installer.cdn.mozilla.net). Rather than my receiving the expected message saying that 60.0.2 isn't supported on Windows XP, this installer, too (once it's used some amount of both CPU and storage), is simply suspended occupying 2,544KB and staying silent.


The following may or may not be relevant.

1. Running any of these installers (and also firefox.exe itself) from a CMD window confirms instant termination. Even from the CMD window, it remains the case that the installers create a process occupying c. 2.5MB. (I didn't try Firefox Setup 60.0.2.exe from the CMD window.)

2. Things are essentially the same in Windows Safe Mode, with the following differences. (a) The 306 KB installers occupy slightly less storage: c. 2.2 MB instead of c. 2.5 MB. (2) Clicking on the Firefox shortcut and selecting "Run As" with the same account produces the message "A device attached to the system is not functioning"; a 'Web search for his message turns up nothing relevant.


The current situation is that Windows was restored to the most recent checkpoint, June 6, as in the second paragraph (although obviously Windows has taken later checkpoints, so that the June 6 checkpoint has been overwritten), and Firefox is installed. Firefox still won't run, and none of the installers produces any output.

FWIW, I'd wondered whether Firefox might simply be refusing to run any longer on Windows XP, but recent tests show that the Firefox-based TOR browser runs from a memory stick just as normal.

We have a client that used to run on local computers running the latest ESR version, they recently changed to a terminal server environment and during the setup 59.0.1 made it onto their new setup. Multiple issues have arisen that were not present on the old system and we need to move them back to the ESR version on the terminal server environment. I read online that you cannot just directly import any profile versions 55.0 and up to earlier versions so I am asking if I can instead use a mozilla account to sync over their data instead without causing a catastrophe, and if anyone happens to know what I might expect afterwards if this could potentially work.

I have to use Windows 10 (Home v:1703).

I'd like Firefox to be my default browser, but it's not listed in 'Choose an App'.

There's just Microsoft Edge listed, along with Internet Explorer, and an option to choose an app from the shop.

Microsoft Edge is also presumptuously shown as the default app to start with.


If Firefox isn't listed, how can I set it to be my default browser - or, isn't this 'allowed' in Windows 10 ?

Several days ago, my Firefox stopped working. I would get this response: Hmm. We're having trouble finding that site. We cannot connect to the server at package.onesearch.org. I tried quitting Firefox and re-opening - with same result. I tried removing all Firefox software/icons from my Mac (Version 10.13.3) and downloading Firefox 58.0.2.dmg and followed the How To Download and install Firefox on Mac instructions, but the end result was a blank page from package.onesearch.org/ followed by a lot of characters. I did notice that the steps the download took me through differed in many ways from the How to Download instructions just mentioned above. When I try the Troubleshooting Information - Automatically add button, it takes me to an Add Ons screen with We're sorry, but we can't find what you are looking for. When I try "try these manual steps", there is no menu item called Help. In fact, there are no menu items at all. This is very frustrating. I am not tech savvy. I am 70 years old and live in Lexington, Nebraska, USA.

Hello there. I tried to update Firefox to 58.01, but since updating my antivirus appears to block the firefox.exe.

I uninstalled Firefox completely, then tried to reinstall it but again my antivirus blocked it before I could open firefox.exe

I reinstalled Firefox again, this time disabling my antivirus and Firefox.exe appeared to work again, I was browsing and redownloading my addons. Once the antivirus enabled itself again after 10 minutes, the same problem happened. Firefox shortcuts couldn't find the Firefox.exe, and in the main Mozilla folder, firefox.exe had become firefox.exe.sig

When trying to uninstall it after this happens, I can't uninstall it through normal procedures unless I rename firefox.exe.sig to firefox.exe (which is also unable to run, says it isn't the proper version when it is)

Would appreciate some help here, thank you

Hi all,

I rely heavily on FireFox (primarily for the multiple profiles and extensions it provides), so deperately trying to solve a problem I'm having. When I launch Firefox on my Mac (10.12.6 - Sierra), I immediately receive an error: "Firefox quit unexpectedly."

I've tried a number of different approaches to resolve including:

1) Starting Firefox in safe mode (by holding down the opt key on launch) - same error occurs 2) Removing Firefox from the Applications folder, and removing Firefox folder from the Application Support folder under the Library (which also removes all my profiles). Then reinstalled Firefox 57. - same error occurs 3) Tried installing older version of Firefox - version 56.0.2 (after removing previous installation as per step 2 above) - same error occurs 4) Tried a machine restart (very early on) - same error occurs.

I've run out of ideas, and hoping someone may be able to shed some light or suggest further troubleshooting options? Desperate to get it working again!

Cheers, Mark

Hello, I've been trying to install the latest firefox on my pc running windows 7 home premium, 64bit. I have cleaned the pc with ccleaner, run mutiple scans with malwarebytes and commodo antivirus, uninstalled old firefox programs and deleted as many junk files and programs that I could find. I have also tried to download with Expolorer rather than Chrome ...All to no avail. The following message details accompany the window which displays.. "firefox has stopped working", and firefox never opens to get to a "safe mode". I have used firefox up until a few weeks ago when an upgrade attempt failed. I would really like to use firefox again, but can't seem to resolve this issue. Your help would be much appreciated. Joe
