Uninstalling Firefox 102 and re-install 78

I downloaded the latest firefox version. It downloaded and replaced my previous firefox 78. Then it won't open because doesn't work with my OS El Capitan. Now I'm stuck without my previous firefox and unable to get it downloaded again. So why didn't the download application warn me that my OS wasn't compatible like other updates usually do? And if I do finally succeed in getting re-installed (how?), will I have lost everything - bookmarks, logins, etc.?

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. Current releases require Mac OS X 10.12 or newer.
