Installing Older Versions

Issue/Question

How do I install a version of Firefox other than the most recent release?

Resolution

Using old versions of Firefox poses a significant security risk.

Mozilla has a website that hosts the installer files for old versions of Firefox which can be found here: https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/.

  1. Locate the desired version number that you would like to install, and click on it.
  2. Select which operating system to download the setup file for.
  3. Select the desired Language.
  4. Select the desired setup file to download.
  5. Once the download has completed, run the setup file to begin the installation process.
