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?

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.

bold text I am booting up an older Windows 7 tower computer and wish to know how to update both Firefox and Thunderbird? The update popup seems to be stuck in download phase.

After the last update a couple days ago Firefox does not come up correctly. Search doesn't work. Duck Duck Go seems to be the default search engine and Google is missing from the selection list when the left mouse button is pushed. I really don't know how to describe the problem. It does come up in troubleshoot mode more-or-less correctly. Something odd happened during the update. A screen came up with some sort of message about having run into some sort of odd problem and that it would have to stop and restart the process, which it did. Hasn't worked properly since.

Tried to update Firefox. Got the message: your updates are being managed by your organization. I'm a home user. No organization. What is the problem? Thank you in advance.

So I updated to Sequoia on my Mac and have run into a variety of problems, i.e. Instacart won't open at all, Amazon has slowed down significantly, can't access my health insurance site (stops at login) and now today Firefox has an update but nothing is actually happening. The wheel just spins and spins and now everything on my machine has slowed to a stop. So my question is how do I stop the update from happening right now?

Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

I "create a new profile" days ago what I first received the notice to update. It seem to work except when I click on a url to view. I received instead the notice that I am in the old firefox and to "Update". I did again and it seem to work until I clicked a url to view and again received a notice to "update by creating a profile.

It's very frustrating - Now I can't open firefox at all. It wants me to "fix it" or create a new profile"

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?

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,

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?

Lately when I manually check Firefox for updates. From the menu Help, then About Firefox. It will download the update, ask to restart Firefox. It will restart Firefox, but NOT install the update. It continues to fail to install until I close Firefox myself, wait a good minute, then load Firefox again and it will install the update. I can make this happen to every computer with Firefox installed.

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?
