your updates do not work and repeatedly we messages to update your browser that never does update! so do we have to delete this Linux program to replace it with something that actually works or are you willing to fix the glitches in your system?

Mozilla support articles frequently state that Firefox does not use popups for browser updates. However, I periodically receive popups from the toolbar stating that Firefox couldn't update automatically. The attached picture is an example from the web but looks just like the popups I receive. The issue typically either resolves itself or I download from the Firefox website and reinstall. In a rush/moment of weakness, I recently clicked the link in the popup. It took me directly to the Firefox website where I regrettably downloaded and updated the browser. I've since run multiple Norton and Malwarebytes scans, which have found no issues. It may be a difference in the definition of popups (from the toolbar vs within a browser page)... Is this a legitimate update message from Firefox? If it is not, are there any other steps I should take (e.g., reinstall Firefox)? I appreciate your help!

Why hasn't firefox 147.0.4 updated to firefox 148 ? The computer is windows 10 home 64 bit that is enrolled in extended security updates. The update has been released a few days ago I believe, in Canada,also I;m wondering if there is a button that is available in "about:config" that forces a update check. Thanks James

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...

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"

Downloaded an update of firefox. Is this for real? A message box came up and said I would get a NEW version of firefox but all my things would be saved. Now I have two firefox versions. My old version has all my info and saved and/or chosen settings. HOWEVER the newer version is a new install without settings and WORSE it has GOOGLE as the browser?!?! Is DUCK DUCK GO gone to goOgle? If I wanted a shopping app I would use my GOOGLE account instead of Firefox. How do I fix this?

Apologies for the non-descript subject line, but it is accurate: I just attempted a normal update to firefox. The first problem once it relaunched was that it did not show any of my tabs that had been open; it just showed a single "new tab" page. Upon typing any URL, though, the browser does nothing. More specifically, it does not initiate ANY network traffic (according to Little Snitch Mini). I tried various things (redownloading and reinstalling, rebooting, and refreshing firefox), but nothing helped. With the "refresh firefox", the only result is that, after a minute or so, the crash reporter comes up.

Curiously, on the prior update to 140.0.4, I had exactly the same issues. I did manage to resolve it by retrying things the next day and the "refresh firefox" seemed to be the thing that fixed it.

A new issue with Firefox. I download updates myself, not automatically. This morning after updating, I clicked to restart Firefox, and it restarts, but still shows that it needs to restart. Even after multiple attempts. How to resolve? Thanks

Every once in a while, Firefox stops allowing me to navigate to any new websites, instead giving only a page that says:

"Restart to Keep Using Firefox

An update to Firefox started in the background. You’ll need to restart to finish the update.

Your windows and tabs will be quickly restored, but private ones will not."

I have automatic updates disabled in Firefox settings, and I have gone into about:config and set app.update.auto.migrated to false, and yet this issue persists. It seems like Firefox is ignoring my preferences. I don't wish to restart Firefox while I'm in the middle of a bunch of work. How can I get past this message and continue using Firefox without restarting? Do I need to delete update files or something?

This random surprise block to my work is ridiculous. We need the flexibility to update/restart Firefox only whenever we're ready to.

Firefox was updated on my computer on 7/23/25. I can no longer access some of my applications. I tried Outlook and everything worked fine. Help me out here, everything was working just fine before the update, and I want to return to a working version. Thanx.

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.

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

Simply put, I continue to get a message window telling me to update Firefox. I continue to get a response saying I need Windows 10 or later installed. I am running Windows 11 Home on my PC. Multiple attempts to get a reply on this from Mozilla Support. No replies.
