I did not have that update installed, I didn't install any Server 2008 updates because when I installed all of them, installing the extended kernel caused a large number of issues (including switching my cursor to the Windows XP one, changing to the classic theme, an explorer error whenever i log in, search in the start not working, and things that require admin not working.). I tried installing just KB4493471, and it did not make any difference, Firefox 110 is still the newest version that's working.
