Was there any Webkit based Firefox or is it UA spoofing?

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

It may be a bot, UA switcher, some old fork, or perhaps someone has found it in random reddit thread and overridden default UA years ago.
