no display & no options
web pages don't display but address is shown at tabs, can't see options but other menu options seem to be okay. I uninstalled and erased all related data (I could find) multiple times and reinstalled multiple times but problem remains. I tried refresh, safe mode, etc. At installation I get error VCRUNTIME140_1.dll not found, a susequent installation finishes without errors. I am sending this from another system because I can't use the problem unit for this post. The problem system is similar to this one. I am puzzled and seek help.
Further, after comparing the installed versions of Visual C++ at these two systems, I noticed 2015 & 2017 were missing at the failing system. How this happened is beyond me. Anyway, following "cor-el"'s suggestion I installed "Visual Studio Community 2019" and Eureka it works again.Read this answer in context 👍 0

do a windows search of your disk for:
there should be a bunch of them, plus 1 in the Mozilla FF folder
You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
See "Visual Studio 2015, 2017 and 2019":
The working system and the failing system has the same occurrence of VCRUNTIME140_1.dll (two entries)
The file might not be registered properly.
Did you try to reinstall this component ?
