I accidentally deleted Firefox ESR that worked fine for years on my old Macbook Pro laptop (2009) running El Capitan OS 10.11.6. Now I can't reinstall it unless my OS is a minimum of 10.12. I don't want to mess with attempting an OS upgrade for fear of losing files and photos. This computer is strictly a nostalgic backup that I would like to keep functioning for a while longer. Any way around this?

Firefox 78.15.0 is the last version for your Mac OS X platform (update channel: mozilla-mac-eol-esr1) and you will no longer receive updates, so you are out of luck if you can't update your OS.
