You can use www.getfirefox.com and click on the green download button, which should take you to http://www.mozilla.org/en-US/products/download.html and start a download of Firefox for the operating system you are using.

See Installing Firefox and find the article that applies to your operating system. if you need help installing Firefox.

When you go to http://www.getfirefox.com/ it should redirect you to the download page and a green button should appear if the site can detect your operating system correctly.

As an alternative, you can try this page where you choose your own operating system and language from a long list of available options:

http://www.mozilla.org/firefox/all.html

(ha ha, 40 seconds too slow!)

Thank you. the www.getfirefox.com redirected me to the Different by Design page with no Green button and more run around, but the http://www.mozilla.org/firefox/all.html did the trick. I usually don't have problems. But this time I was stumped. You guys are very fast. Thank you so much.

Thank you. the www.getfirefox.com redirected me to the Different by Design page with no Green button and more run around, but the http://www.mozilla.org/en-US/products/download.html would have done the trick (I went there to checkit out), but I had already gone to http://www.mozilla.org/firefox/all.html. The other post was at the top of my inbox. You guys are fast. Thank you so much.

"Different by Design" is just "brand messaging" for the Firefox download page (shown here and in the How to install Firefox on Windows KB article) for marketing purposes. It's possible that the browser you were using had JavaScript disabled (or you're using web-filtering software that blocks scripts) because when I disable JavaScript and go to www.getfirefox.com, the page I'm redirected to, which is http://www.mozilla.org/en-US/firefox/fx/?from=getfirefox doesn't have a green download button.
