I have Firefox 60.4.0 esr on my other laptop
and having difficulty finding the download for
Leap 42.3 Firefox rpm
MozillaFirefox-60.4.0-125.1.x86_64.rpm

When I use
https://software.opensuse.org/package/MozillaFirefox
it only installs 52.2.0 esr

I really want the YAST or rpm or zypper command to get 60.4.0 esr

Thanks in advance !
