Is 'Firefox 45 esr or newer' available for SLED11SP4?
The latest Firefox version is 38.7 (SUSE released it on 15-3-2016) that i see in the SMT Repository:
Mar 15 2016 MozillaFirefox-38.7.0esr-37.3.i586.rpm

Unfortunately I don't see newer versions in the repository.

NCC/SCC mirror credential is valid.
The mirroring is enable and runs everyday. (I don't see any errors)

Thanks for your advice
