A critical fix just installed. But it did not behave like a normal update. It opened the command prompt, installed then just sat there. Was that a virus or FF?

A critical fix was just installed on my machine. The web page I was looking at was replaced completely by a FF page. Looked official but the notice was not how I am normally notified of an update, but then again it said it was urgent. Then the update itself did not install like a normal FF update. The update started, it opened the command prompt window, installed something and then just sat there saying the update was complete. I fear I downloaded a virus or malware to my machine that was disguised as a FF update since this is not how a normal FF update behaves. Also this is a new machine. I downloaded FF for the first time to this machine only a few days ago. So the question. Was this really FF or was it malware? Thanks.
