Mac Mini (late2012) OS X El Capitan 10.11.6 refusing to work with firefox

Downloaded the latest version of firefox. When it was opened and it went through the verification process then to move firefox folder into applications for use we received a notice where the firefox logo had a circle with a line through it (indicating to us that is would not function) then an arrow pointing to the application folder. The firefox version downloaded and opened Firefox 91.8 Oesr.dmg

Any suggestions as to what safe version I could use on a mac mini late2012 operating OS X El Capitan 10.11.6 Which I am told is the latest version that can be used on this machine with the following characteristics: processor 2.3 GHzIntel Corei7 memory 4GB 1600 MHz DDR3 Start up disk el capitan 10.11.4 this is strange since 4 lines above it states OS X El Capitan Version 10.11.6 graphics Intel HD Graphics 4000 1536MB

Your suggestions would be welcome.

Thanks
