I cannot understand what your problem is due to lack of information but the solution to your problem is a download mirror.

edit: replaced the two random unofficial download sites links with a official link.

the solution to your problem is a download mirror.

Certainly not. Firefox should always be downloaded from Mozilla directly. https://www.mozilla.org/en-US/firefox

Please do not post links to third party sites for downloading Firefox.

Nothing happens when I click on Download from Firefox home page

Can you post a link?

If you cannot download it from a 3rd party you can atleast download it from

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

The File Repository of Mozilla

Try this:

• Download the Firefox installer and save the file to the desktop
  https://www.mozilla.org/en-US/firefox/all/
• Start the installation with a double-click on the desktop icon

Note that is is best to use the CDN server and not the FTP server if you want to post a direct link.
