Firefox wont update, gives error when trying to

more options

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!

The "stub" installer doesn't work for everyone, but usually the full installer does. Unless you have malware that blocks Mozilla sites, it is strange that none of the downloads work.

Could you try downloading the installer for Firefox 115.0.3 from this server (I suggest this because I'm not sure it's safe to jump from version 107 all the way to 133 in one step):

https://archive.mozilla.org/pub/firefox/releases/115.0.3/win64/de/

After installing that, hopefully Firefox can start updating itself again. If not, you can try a later version, etc.
