I download the new Firefox version from mozilla homepage.... while unpacking or clicking the exe-file there is a error message, that a file isn´t found. Then I unzip manually and try to install the setup.exe with the same result. Directly after the message my other browser opens a mozilla site (https://www.mozilla.org/de/firefox/installer-help/?channel=release&installer_lang=de) and another message that the download process is ended and it stops.

What should I do? I try it in different ways maybe 10 times with the same result

OS: Win 10 pro 64 Browser: Google Chrome last time I downloaded and try to install with IE Delete all downloading files, cookies and temp. files enough free space to install what is the problem and how can i fix it?

These are the standard install instructions for Windows

That pasteable link should be a full ca 40MB installer. It sounds as if you are using a stub installer that does not download the full file straight away, and then causes you problems with the download.

Good luck. Please post back to say how you get on.
