Firefox no longer works after uninstalling Mozilla VPM

I uninstalled Mozilla VPN and then it got a runtime error. After trying to refresh Firefox I was forced to do an uninstall and clean reinstall. However now it doesn't even load. Fortunately Chrome is still working so I can get online and ask this question: how do I do a full reinstall to get a browser that loads? I'll be happy to run any diagnostics that I can.

Hi Rick, do you recall what the error was?

Sometimes program installers and uninstallers mess with certain shared Microsoft files, triggering a message related to a missing VCRUNTIME140_1.DLL file. That can cripple Firefox.

To rule out that issue, you can (re)run Microsoft's installer for the VC Runtime files:

(A) Open https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

(B) In the first section of the article -- "Visual Studio 2015, 2017 and 2019" -- download the 64-bit installer.

(C) Run that installer and restart Windows.

Any improvement?
