I could successfully run Firefox 52.9 using the Kernel Ex core updates and the kstub824.dll library (as well other requirements from the subforum related to this topic). However I can't longer run Vlc 3.0.16 and an error message always pop up (from Kstub824), which made me guess that kstub824.dll was the culprit. I found a temporal solution by removing the kstub824 argument on BASE and DCFG1 from the core.ini file and after rebooting vlc worked again!
However, I don't know how to create and exception in the core.ini file where kstub824.dll isn't loaded when running the vlc.exe file , any ideas?
