Firestorm older viewer for Mac

[ItHadToComeToThis]

Does firestorm still have the older viewer it was maintaining for older versions of Mac OS?. I have installed Mavericks on my old MacBook Pro Retina but it doesn't really support newer versions of SL. Im not too fussed about the new features and whatever else that I would be missing out on. I have Mojave installed on another partition so I still have access to all of that. I am reverting back to an older OS to see how much more friendly it is on the hardware in this model compared to using the newer OSX. And I could do with a copy of the firestorm viewer that they were maintaining for older OSX releases to test a few things without all the bells and whistles of the more modern viewers. I did try looking on the firestorm website but I could find anything but I do remember it being mentioned in the last year as still being available for download.
