I am using Mac OS X 10.15 Catalina. That is the highest OS I can use with this Mac. What is the highest Firefox I can use?

You are in luck as the minimum requirements for Firefox on macOS since Fx 116.0 has been macOS 10.15 so you can use the current Firefox 131.0 Release from https://www.mozilla.org/firefox/all/desktop-release/osx/ as just pick your language and download and install the dmg.

FYI in my experience this isn't true. There's been a bad bug on Catalina for several releases now, where many of the menus don't work (settings, bookmarks, translation, manage extensions, update reminders). I assume it's all the same component.
