I have Windows 10 a decent Lenovo laptop

I am fed up having to update firefox every single day !! Is it not completing the update or is there some glitch that keeps occurring ??

I have used FF for quite a while and ignored MicroSoft Edge... but I dont know how much longer I can carry on with this slowdown !!

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

Je suis constamment interrompu par le pop up suivant, comment le faire cesser? "Contrôle de compte d'utilisateur. Voulez-vous autoriser cette application à apporter des modifications à votre appareil? De Firefox Soft ware Updateur. Editeur vérifié: Mozilla Corporation. Origine du fichier: Disque dur de cet ordinateur." Pourtant dans les paramètres on indique que tout est à jour et aucune action n'est requise. Comment le flusher sans qu'il réapparaisse à tout moment et comment puis-je m'assurer que ce n'est pas de l'intrusion ?

Want to roll back my latest update. all my saved items on home page,bookmark and history tiles vanished. Firefox shouldnot give two rips what browser I am using be it: Windows 10 11, 13, 7 ,or ME

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.)

Every time I log into MOZILLA_FIREFOX it asks to update. I have tried this before. I usually just hit that NO button...When I do click on the YES button & try to update...IT WIPES OUT EVERYTHING I HAVE STORED ON FIREFOX. EVERY SINGLE PASSWORD...SHOPPING LISTS...I'm done! I now once again have to go and recover all my information. Thing is....it updates automatically........so WTH is going on? I will start looking for aother browser...is this a scam or what?

The details:

1.) After downloading the update, my antivirus scanner reports an infected file (see screenshots / message + path).

2.) When I try to “Restart Firefox to complete the update,” Firefox briefly “disappears” (whatever happens there) and then “reappears”—but the prompt “Restart Firefox to complete the update” is still there. Unfortunately, this can be repeated as many times as you like without anything changing.

3.) Restarting the computer (Platform: macOS Tahoe 26.5.1) does not resolve the issue either (see screenshot). I always performed previous updates before shutting down the computer—and the next day (since Firefox, as expected, had been closed and restarted), the updated version of Firefox was running.

4.) The suggested solution is to download the “Firefox installer.” But that doesn’t help me, since I need “Firefox DEVELOPER.”

Would uninstalling Firefox DEVELOPER and reinstalling it >WITHOUT DATA LOSS< be a solution??

Everytime I open firefox, a small window opens that tells me "Update available Download the latest version of firefox, Download or Dismiss". Hitting download saves the update for ver 151.0.4 to my harddrive. I have several of these files because of all the times I've updated forgetting that its already been updated to 151.0.4!

Why do you keep asking me to upgrade when I already did?

To get here I went to "mozilla support" and I clicked the box requesting you send me an email when someone replies to this. This "someone" implies that this person is part of your "community" not a mozilla employee, which is what "mozilla support" implies. After taking my time to follow your vague directives, I dont expect to get any help from you but I am hopeful.

I tried adding images which took me away from this page and when I tried coming back to this page, everything I typed was gone so I had to start over. So I'm not going to click on "share data" for the fear the same thing will happen. Thanks for that

I frequently get a notification that an update failed to install and to install it manually. When checking the update section in the settings I see "Restart Firefox to install update". After restarting, the same section shows "Applying update..." but never finishes. This has been happening for a while and it's becoming very frustrating. Any help is appreciated.

One more thing that may be related: sometimes when launching Firefox, the window will pop up for a split second then close and I have to launch it again. This usually happens on a cold start.

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes and a force quit is necessary.

After updating to Firefox 152.0.1 this morning I keep getting Error 7023 Service Control Manager each time I start Firefox. The error description states "The MozillaMaintenance service terminated with the following error: Incorrect function." The Mozilla Maintenance Service was set to Manual and I set it to Automatic but still getting error each time I start Firefox. I have read that the service can be disabled so what do you suggest I do to stop the 7023 error. Thank you.

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.

Ok so a month ago FF updated on four W11 laptops and now every time since then when you open FF it wants to make changes to your HDD and then tells you it can't download the latest version. I've uninstalled it and reinstalled it and its the same across all devices. None of the three devices are running any of the same software aside from the OS as they're all dedicated to different purposes, so I know its not something on the devices themselves. We ended up uninstalling it on everything aside from the older W10 desktop because its a constant nuisance. Each time it updates it is successful and there's no failure messages, so it's not like its obviously failing to update, but something certainly broke.

Firefox will randomly require an admin to install the latest update and then go 10 or so updates without any admin access needed.

Work device, all users are non admin making this extremely tedious to update a browser that brings a new update almost every 3-5 days.

On top of that, I elevated to admin and went to the help > About section and pressed Restart to Update Firefox and entered admin creds and still its refusing to update. Just re-opens on 151.0.4.

On the previous version it did the same thing. I completely wiped my firefox from the system, removed all registry and file settings, rebooted, and did a fresh install.

now on 152.0 its doing the same thing again.
