I am trying to re-install Firefox but seems never to complete the installation. It does not open any websites and does not appear to connect to the internet. Also, I receive a message that the file VCRUNTIME_1.dll is missing; however, when attempting to download the file, it tells me the file is already installed.

What's your computer system and Firefox version?

We are seeing this a lot of late.


Did you see any error messages when launching Firefox, such as "VCRUNTIME140_1.DLL is not found"? In that case, I would 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
