I want to download an older version of Firefox for testing Oracle certified versions (for PeopleSoft PeopleTools). I found the directory of older versions but need instructions for the steps needed to download the desired version, which is version 17. Thank you for your help.

Do you want to replace an existing installed version, or is this a new install?

I'm not sure what site you are using for your download, but there is a link in this support article as well: Install an older version of Firefox ("I still want to downgrade" section).

Which Firefox version do you want to download?

The latest Firefox 17 ESR (Extended Support Release)' for Windows is available here:
http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/17.0.6esr/win32/en-US/

If you will be installing that version on a PC which already has a different version of Firefox installed, you will need to create a new Profile fir the ESR version. Let us know and we'll tell you how to create a new Profile.
