How to Download an Older Version of Firefox

Save

Mozilla regularly releases new versions of its Firefox Web browser. But you can download an older version to test a website or extension using it. Mozilla's official Firefox website doesn't offer download links for older versions. If you want an older version, you can still download it from Mozilla's File Transfer Protocol server. Mozilla's FTP server contains all released versions of Firefox, including beta versions. You can access the FTP server and download from it using your Web browser.

  • Type or copy and paste "ftp://ftp.mozilla.org/pub/firefox/releases/" into your Web browser's address bar and press "Enter."

  • Click the version of Firefox you want to download on the Mozilla FTP download page that appears.

  • Click "win32" on the page that appears to select the Windows release of that version.

  • Click "en-US" on the page that appears to select the U.S. English release of that version.

  • Click the installer file with the EXE file extension on the page that appears to download the installer for that version.

Tips & Warnings

  • Double-click the EXE file and follow the instructions on your screen to install the old version of Firefox. Click a different operating system instead of "win32" if you want an old version of Firefox for Mac OS X or Linux. You might have to double-click files and folders on the FTP site if you're using Internet Explorer instead of another Web browser.
  • Old versions of Firefox have security vulnerabilities; avoid using them as your primary Web browser.
