I have received the 14 Jan Mozilla Update warning a few times now, and I have tried to update Firefox, but it seems my computer sytem is now too old - iMac 0X El Capitan 10.11.6. PLEASE NOTE, I have an iMac from early 2009 and I am now unable to update my system to any other Mac version.

I lost all my saved pages and bookmarks recently when I tried to update Firefox using the instructions online. Unfortunately it was only after updating removed old Firefox that I was then informed that I would not be able to use the new version with my computer. I was able to resurrect my old Firefox from a backup, and would like to continue to use it as I am very happy with Firefox as a browser.

Are there any work-arounds that would allow me to use Firefox on my iMac - it is working perfectly and has just been cleaned and I've had a new hard drive installed - it seems incredibly wasteful to have to buy a new computer! Yours hopefully!

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.

Hardware: Macbook Pro (Apple M3 Max) OS: Sequoia

I have OLD imacs. The one I'm on now says 2017 and according to some homework, the latest version of Firefox I can run on IOS 10.13.6 is version 115.

WHERE do I FIND that?

I went to mozillas page and there was only one place to update firefox. I went ahead and tried, then got a pop up saying to restart.... did. Then got some helper thing suppose to download, put in my computers password, and NOTHING seems to happen. Nothing at all. Downloads like this usually involve a spinning wheel, or bar showing progress, SOMETHING. I didn't get anything.

Restarted firefox, and every time I go to about firefox to see if it updated, the same pop up shows up. (Will attach a screenshot of it.)

If I look under applications/firefox, it has NOT updated at all.

I'm guessing it's updating to the latest greatest version which MY computer cannot run. SO where do I find VERSION 115?

Ok, I can't reinstall Firefox because I have data, links and other that I no longer have access to link website links.

What is the next solution please as Firefox is my default and main browser.... or is it time to move away from firefox.?

I tried to import date and others however it was not an easy task to do, and I have to System Restore to once again get the Error that stops Firefox, is there a way of undoing the update that firefox installed ?

I received a msg from Mozilla that my Firefox was out of date and to download current version. I downloaded the current version but it does not update. I went to the menue and firefox help and it said automatic downloads disabled by system adminiestrator, I'm running linux mint. How do I get the download to update?

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'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.

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?

Windows 11 23H2 FireFox 136.0.1

When clicking check for updates it firstly shows the rotating arrows icon for a long time and then says "Failed to Check for Updates"

I've completely reinstalled Firefox and this continues to happen

I do not have NordVPN or any other VPN installed

The behaviour is the same in troubleshoot mode

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

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?

I read there is a need to immediately update Firefox. I down;loaded it, but got a message that a newer version exists...? Also, it shows my latest update was 11/24. I use auto updates and recall one much more recently.(in fact I found the new tabs annoying) I am perplexed.

Good Morning! :)

I have a note book HP, which windows operating system was erased back in the past, I happily use mozilla. This device I use it exclusively as a monitor to watch TV.

I got the notification of the Mozilla update, I have downloaded many times in the laptop: firefox-136.0.1-tar.xz However does not run or execute the file and update the system and laptop. I am able to open the file, but that is all.

Please let me know what I am doing wrong to fix it.

Thank you very much for your attention
