1. The latest FF is installed (80.0). May I delete FF (78.0.1) and Mozilla Maint. Service (78.0.1)? 2. May I speak in Russian?

Did you use the full installer, or let the browser update? If you let the browser update, it should replace the old browser with the new.
I use the new browser. The question is: may I delete the version FF 78? that is preset in my system?
Yes, you can.
