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 ?

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

So I need to update my Firefox Browser to 128 BUT somehow "Updates disabled by your system administrator." and as I am the only user I have never set up an administrator.

So I have had a look and I don't understand most of what I am reading.

So about:policies.... DisableAppUpdate true So how do I change that? I have looked at Reg Editor but have no idea what I am looking at.

It took me a long time to update to Firefox 121 because I did not like some of the changes Mozilla did to it like spacing between Bookmarks in the dropdown so to update again is a big thing for me. Attached as much as I think is relevant. Any help will be much 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 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?

Hi there, Im on a windows 10(ish) and yesterday got this problem after the auto update to firefox 133.0.3 - Update is not working. error window says platform version 133.0.3 is not compatible with minVersion >= 133.0... how can I fix this?

I've seen that there was a similar issue back in October with a previous version. Tried to follow instructions and reinstaled firefox from mozilla. But the problem is still there. Restarted after reinstalling and still getting the same error message. ((( Please help )))

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

Hi - Happy Holidays!

When I open Firefox for the first time each day I get this error message

Error: Platformversion 133.03.03 is not compatible with: minversion:>= 132..02.02 maxversion:> = 132.02.02 Maybe try to reinstal Firefox?

I have not tried to install because don't know if that would solve the problem and I'm afraid of losing bookmarks

I have used firefox for several years. Lately I have consistently gotten a message that there is an error and Platform Version 130.0 is not compatible..... I have followed several suggested remedies on the Internet with no luck, with the most consistent remedy being to reinstall. Thjat hasn't worked. Do you have a solution or should I just go to another browser?

If you select No to the UAC prompt when updating Firefox via Installer, it will install Firefox to "AppData\Local\Mozilla Firefox" without telling you, instead of overwriting the copy in Program Files or erroring out. Additionally it will create a new Profile and set this new Profile as the Default Profile without telling you. Lastly, it'll remove an existing Pinned shortcut on the Taskbar.

So you've now got 2 copies of Firefox installed, one of which you're not told anything about and an additional Firefox Profile with no indication that this happened nor any instructions on how to undo this nor how to change the default Profile.

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

Hello,

When I attempt to open Firefox, I am getting a pop-up screen saying:

135.0.1 not compatible with min version >= 135.0 max version <=135.0

Also, I am being advised to reinstall Firefox. Do I need to uninstall Firefox first?

Windows10, Dell Laptop

Thank you,
