hello, mozilla doesn't offer phone support - but we will try to solve your issue here on the forum. can you please specify what exactly isn't working - does the download fail (how are you downloading it, any error messages) or is there a problem during the setup procedure?

Yes, you need to explain the problem better, to see if the issue is the download itself or an installation problem. See How to install Firefox on Windows for basic instructions.

If you can't download the Firefox 13 setup file by going through www.getfirefox.com/ try one of these download pages:

• http://www.mozilla.org/products/download.html
• http://www.mozilla.org/firefox/all.html

(I'm suggesting these alternate download links because it solved another user's download problem, reported in this recent thread.)

P.S. Also make sure your Windows XP system meets the Firefox 13 System Requirements (you need at least Windows XP SP2). See:
