Hi @lavablast44, you're very welcome! Thanks for the patience. The script suite and instructions will be coming your way around midday today! Yeah, if you already know how to install an older version of Firefox, go ahead and do that (documentation/instructions included if not). We currently don't automate that process, since our script suite is actually just based in the Selenium IDE. But once you have Firefox 50-54 downloaded, it is essentially plug and play! :)
