Please make sure you use an official link such as '''getfirefox.com''' or a direct mozzila link: https://www.mozilla.org//firefox/desktop/ You mention using multiple links and I worry you may be using scam or malware links. Please see this article * [[How to download and install Firefox on Windows]] Note if you get Firefox 47 it will shortly update to Fx48, again make sure you use the official method see * [[Update Firefox to the latest version]] if you are having difficulty downloading Firefox due to 404 errors check out these links * Firefox's own site reports status.mozilla.org *A third party checker http://www.isitdownrightnow.com/mozilla.org.html <== TAKE CARE it should correctly report whether the site is reachable, but it may have unreliable adverts etc on the site.
