Hey.
I just happened to be around here and I wondered whether you are aware about how this site's login page looks, for some time, in sort-of-recent Firefox (such as 78.8.0esr).
In short: The layout is very "interesting", and you really like Social Media!
The only way to truly showcase the problem is a print of the page as I see it (a single screenshot just doesn't do it justice), so attached is a multi page pdf.
All the best!
p.s. the login still works though, despite the layout.
