I can't seem to update to the latest version of Firefox.

Steps on macOS 15.2: 1. In previous version of Firefox, get dialog to update to current version of Firefox 2. Click Restart to update Firefox. 3. Enter admin user name and password to allow Firefox to install a helper 4. Got a request to let Firefox access my devices. My devices are not Firefox's business, so I replied Don't allow. Note: 3 and 4 may have been swapped.

Expected result: Get a dialog that Mozilla corp has installed something; Firefox relaunches with the new version

Actual result: Get a dialog that Mozilla corp has installed something

Attempted workaround:

5. Click Firefox icon in the dock

Expected result: Firefox launches

Actual result: Get dialog asking me to enter admin user name and password to allow Firefox to install a helper.

6. I do so.

Expected result: Get a dialog that Mozilla corp has installed something; Firefox relaunches with the new version

Actual result: Get a dialog that Mozilla corp has installed something

Attempted workaround:

7. Click Firefox icon in the dock

And I get a strange feeling of deja vu as the process repeats and I am unable to launch Firefox.

If I look at the macOS console and filter on Mozilla, I notice these two messages from org.mozilla.updater:

1. Server doesn't exist or doesn't provide correct selectors.
2. Failed to connect to update server after several retries.

I have no idea how to proceeed.

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.

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.

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.

I had renewed my subscription for MS365 on Tuesday the 30th when I got a popup inviting me to update Firefox to the latest release. I agreed and the download appeared to have worked. However, I soon found I could not access any of the MS365 apps. I restarted and found Firefox had also disappeared. The icons are present in the list of apps but clicking on them gets no response.

I have deleted and reinstalled Firefox and downloaded a new MS365 with no change.

I have Norton online antivirus and the MS365 comes with continuous Defender using Malwarebytes. (I am running down the remaining Norton subscription). I have also used both to do a sweep on each but no problems were found.

I have Outlook which has not been affected.

I am coming to the conclusion that I may need to do a full deletion of both. Can anyone suggest any other way to deal with this?

All I have is an older windows 7 dell laptop and firefox was working ok but then it said firefox must be updated by march 14 so i clicked on the update but it has been over 24 hours and the little circle is still going around with 0 results why

After easy semi-automatic updates for many years, the last two updates (143.0.3 and 143.0.4 on Windows 10 64bit) have stuck showing "Downloading update -- 0 bytes" for hours. The first time I eventually gave up and used the installer from the Firefox site to re-install. This seemed to get me to 143.0.3 without losing any important data in my profile but was certainly the hard way!

Now the same thing is happening during the update to 143.0.4. What's going on? Are other users having this problem? -- jclarkw

P.S. -- How can you manually stop and update during the download process? -- jclarkw

Last night the 15th January 2025, the firefox decided to update, buy it self closing the browser, however when it restarted it now comes up an Error, something along the lines of 134.0.1 and 134.0 MinVersion, if you have seen this you will know what I mean, it suggested to reinstall firefox, with that I did and I tried to porting all the setting and data and every thing, however it didnot import.

Where can I find the previous version that generated the error to start the import again... as there are links that I simply can not get any more

Cheers

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.

Hi Mozilla friends,

I'm running OSX 10.9.5 and I just can't afford to buy another computer right now, all the more that my iMac works beautifully. I tried and cannot install the current Firefox. What am I to do? Many thanks, - Greg

I have taken the position of never installing updates of firefox in windows 10 because of the following: after EVERY update, within 20 minutes of activity my mouse freezes. Keyboard is inactive. I have no option but to reboot. Windows displays "repair mode" 2 HOURS LATER ! the pc finally boots. This happens after EVERY upgrade. Since I have stopped upgrading, the pc behaves.

Hallo zusammen,

ich kann meinen Firefox nicht mehr aufrufen, weil er wohl nicht kompatibel mit 133 ist. Es wird empfohlen zu deinstallieren und neu zu installieren. Aber dann sind meine Favoriten, Lesezeichen und Passwörter weg. Ich kann sie nicht sichern, weil ich keinen Zugriff auf die alte Version habe. Wie löse ich das Problem?

Viele Grüße Annette

Hello everyone,

I can no longer access my Firefox because it is probably not compatible with 133 (see screenshot). It is recommended to uninstall and reinstall. But then my favorites, bookmarks and passwords are gone. I can't save them because I don't have access to the old version. How do I solve the problem?

Best regards Annette

Dear Firefox Support, My issue is with the browser I use 136.0.1 (64-bit). Select Help menu (Restart to update Firefox) I've preformed this task several times so far and I keep getting the something over as I click on Help menu. I restart the browser again however it is the same thing "Restart" again. What is my next step here?

Thank you, Dave 18 March 2025
