Bonjour, Je ne peux plus du tout accéder à Firefox. Message : Error platform 134.01, is not compatible with...

Je n'y connais absolument rien en informatique.

J'hésite à faire une ré-installation car je ne souhaite pas perdre des données.

Pourriez-vous me renseigner, svp ?

Je vous remercie

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 ?

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

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?

My main, daily used computer updated to FF 134.0 when it was released. Two other computers that are less used will not. All are Win10. The two computers were booted up this weekend, but when you try to check for updates, it says they are already up to date. Both are 133.0.3 and have never had update issues before.

Was the 134 update pulled for some reason?

I know I can probably manually download and install the update, but am worried there may be problems with 134.

Hello, I'm having some problems with updating firefox. It started a few months ago that I got a Pop-up every time I started Firefox about needing to update it. But when I click on the prompt to update it, it leads me to this website: https://www.mozilla.org/de/firefox/new/?reason=manual-update , and after clicking on the download button I get to this site for about a second: https://www.mozilla.org/de/firefox/download/thanks/ after which it loads this site: https://download.mozilla.org/?product=firefox-stub&os=win&lang=de which my browser can't connect to (aka just gives me the standard error message as if you entered an invalid URL). Today I got this website pop-up when starting Firefox: https://www.mozilla.org/de/firefox/welcome/21/ which leads to the same outcome as above. After that I tried to update Firefox by going to the menu -> help -> about Firefox, which searches for updates but then tells me that I have the newest version installed already??? Even when I try to manually install a new version through this site: https://www.mozilla.org/de/firefox/all/ I still get the same result. Please somebody help me out here!

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!

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?

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

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

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

For the third time in a few months I have done an update and it breaks my Windows. My apps stop, my task bar disappears and becomes unavailable. I have to use Task Manager to either sign out and back in, restart Windows Explorer or re-boot the laptop. Then another update comes out and fixes that. But the inconvenience of having to shut down in the middle of a remote meeting is embarrassing to say the leas.

Come on guys. You are better than this - you are Mozilla not Microsoft - don't adopt their bad practices and procedures.

After a new update two days ago, Mozilla will not load. I get the error message: "ERROR: platform Version 133.0.3 is not compatible with miniVersion>=133.0 maxVersion<=133.0 Maybe try to install Firefox". When I klick the Mozilla icon nothing loads. I can't load any icon for a website. Prior to the update everything worked. I need Firefox working.

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 )))
