There could be several reasons why you want to stick with a specific (old) version of Firefox web browser, instead of updating it to the latest version. Some of your favorite add-ons could no longer work after Firefox update; you may want to try out an old Firefox extension which has not been updated for too long a time to be compatible with the latest Firefox; some web application's user interface may no longer be accessible after you have upgraded your Firefox, etc.

While it is recommended that for security reasons, you always stay up-to-date with the latest release of Firefox, you may still want to go back to an old version of Firefox if it is absolutely necessary. It is not very complicated to install an old version of Firefox on Linux. The following is 5-minute guide to do it.

First, download the version of Firefox that you want from Mozilla FTP archive.
