Firefox won't run due to System Error
When I try to run Firefox, I get a window pop up says System Error X The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem. I downloaded Firefox & tried to open it & got the same error. Any suggestions about how to fix this problem & not lose my bookmarks?

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.
Install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads
