Downloaded Firefox Installer seems to be from 2018

duplicate of /questions/1433030 thread.

I‘m somewhat uncertain: I downloaded the Firefox Installer from (I believe) Mozilla.org via Edge. When I tried to Upload the file to VirusTotal I got errors first and it only worked after restarting the laptop.

The file hadn‘t been analyzed so far (which surprised me), 1 out of 72 scanners claimed to have found a Trojan but what bothered me more was that according to VirusTotal the file was compiled in 2018 with Microsoft Visual C/C++ 12.00.8168. It was also somewhat smaller than the last Installer I downloaded (342kb vs. 390kb), although both should be version 18.05.

So I‘m a little concerned if the downloaded file is legitimate?

I‘m sorry, I posted this in the wrong Board, the question refers to Firefox for Windows.
