Firefox Community Forum

I’m facing a strange issue after the recent Firefox update. Whenever I try to install or update Firefox to the latest version, the process stops midway and a small popup appears related to a “challan notification” from a website I recently visited.

After this popup appears:

The installation freezes

Automatic updates fail

Firefox sometimes restarts but remains on the old version

No error code is shown, just the interrupted update process

I have already tried:

Clearing cache & cookies

Restarting Firefox

Safe Mode

Reinstalling Firefox manually

Checking firewall/antivirus settings

But the problem still occurs.

I want to confirm:

Is any website notification (like a challan reminder or traffic-alert site) capable of interrupting Firefox updates?

Does Firefox block updates if a previous session was not closed properly due to such popups?

What is the correct method to force a clean update without affecting my browsing data?

Please guide me on how to fix this issue. Thank you!

Firefox requested helper tool to download after an update & now it will not perform the helper tool to install and Firefox is not responsive and doesn’t start up. I’ve uninstalled it 2x and it will work for a few days then the helper tool install request pops up and the cycle starts over.

Less a question, more a statement. On most updates (every? I don't know) I loose my dictionaries and the spellchecking does no longer work.

Also, after an update the browser just ... dies. I mean it still works but it is if I would have no internet. Usually some tabs die before the others.

So yeah, this little rant hopefully opens a ticket and you guys can check if others have the same problem.

Also if you are wondering why nobody is upgrading. Yeah, that is the reason. I try to delay it as much as possible.

Good day!!! I updated my browser today, and after that, everything I had in it was reset, from my account, open tabs (there were over 300 of them), passwords, themes, and everything else. If you don't know how to properly test your updates, then don't update your browser at all. Thanks to you, I lost a lot of information I needed. Thank you!!!!! I'm uninstalling your crappy software and switching to Edge or Chrome.

Each time I open the Firefox Icon on my desktop in AVD, it opens an older version and it prompts me to recreate a profile. I updated Firefox yesterday and brought over my passwords and bookmarks. This keeps reoccurring after we fix it each time. Can you help?

Several weeks ago, Mozilla completely reset my Firefox. Removed my addons, reset my settings in about

config. I had previously changed a lot of things, specifically stopped all videos and things moving on my page. I searched the net, and changed a few things, but I still have things moving on my pages. Thanks, Mozilla, Brave is looking better everyday. Win7 115.30 oesr I am not happy. How do I send a message right to Mozilla, Hidden and impossible.

I updated to version 146 today on Windows 10 and had to use administrator credentials. I have Mozilla Maintenance Service previously installed. I tried uninstalling MMS and then re-installed FF using full installer and selecting the custom option to install MMS. I cannot see the option in Settings..General 'Use a background service to install updates' (Screenshot attached) How can I fix this issue which has been present for some time?

Yesterday I tried to update Firefox to 146.0, but the update failed, consistently. Here's what I did: Seeing the usual "There is a new update available"-pop up, I accepted. "About" screen came up. I clicked the button "update to 146.0", but no download started. I waited about 15 minutes, but still no download. I closed the window. Next, I tried the menu option: "Help->About Firefox". "About" screen came up. I clicked the button "update to 146.0". Same as above, no download.

Before anyone asks the obvious questions: Yes, I was connected to the internet the whole time. I checked that by calling up random pages. No, my firewall was not blocking Firefox. No, it was not just one quirky device. I tried it on laptop and desktop both. Yes, I did close and restart Firefox, I even rebooted the devices, and tried again. Same problem.

Now while my workaround (see below) helped, there is still the question of the update process failing in the first place. For me, that brings up two pressing issues at least: 1. Has anyone external tampered with the update process, maybe with malicious intent? It has happened to several software distributors, most recently the guy behind Notepad ++. 2. What happened to people relying on automatic (i.e. not prompting) updates? Did they even notice they were not being updated?

Not a solution, but a workaround: I synced all my setting to my Firefox-account (worked just fine, no problems), downloaded the newest installer, installed the new version on top of the old (worked like a charm), started new version, all just fine. I did not even need to sync my settings back, all was kept intact. Excellent!

Every SINGLE time Firefox update now, we have to create a new profile, EVERY SINGLE TIME. We loose all our open tabs, passwords, history, bookmarks, everything.

Why is yours the only browser that does this, and how do we stop this from happening.

This is having an effect that is starting to drive me away from using all your products.

Every few weeks I get this error and my bookmarks and passwords are corrupted. I have uninstalled and reinstalled Firefox, per the full uninstall instructions, including deleting old Firefox folders and it works for awhile and then returns.

Error: Platform version '147.0.3' is not compatible with minVersion › = 147.0.2 maxVersion < = 147.0.2 Maybe try to reinstall Firefox?

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"

I rebooted Windows. Firefox seems to have been updated. But a firefox installer was downoaded. This behaviour is stange an suspect. Do I have to re-installa firefox? Why?

Greetings Ya'll,

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all.

Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?
