The idea of my approach is based on Hay Kranen’s 8-year old post on HOWTO run multiple versions of Firefox side-by-side on Mac OS X Lion. Using different profiles also allows one to run multiple (different) version of The first is easy, for the second it is required to create a separate profile in Firefox and start the legacy version with a parameter to use that version.

Having multiple versions of Firefox running alongside requires to separate them, both their installation location as well as their profile directory (the place where Firefox stores all its settings, plugins, history, etc.).

As I wanted that install kept up-to-date and didn’t want the legacy version to auto-update (as the legacy web interface then also would not longer work). Personally I don’t use the Firefox browser much though I have it installed for the odd site that does not work with Safari (yes, that happens and more and more often). In this post I will describe how I set this up and also how I ensured that the browser would not conflict with a regular installation of the Firefox Browser Yes, one shouldn’t use obsolete browser versions as it is not safe for normal browsing, but to access a web interface of an internal device (that otherwise can’t be managed) should be safe enough as long as one doesn’t visit other sites.

Since the OS that runs on now also is way beyond EOL I worked out a way to use older versions of the FireFox browser (as they keep a great archive of their historic versions). It found out that they worked fine with Firefox 17.0.9esr (yes I know that is really old) and for quite a while I kept an outdated VM available to manage them. I still have a few old web-managed devices of which the web UI does not work (correctly) with modern browser versions.
