@leocg See screenshots again, on Opera it shows mobile header and on Chrome it shows header menu.

Hello, I'm using Firefox to manage my website but when I open my blog in Firefox my site's layout is not showing like the original one with header menu but showing mobile toggle menu on Desktop, in Chrome it's showing with header menu, I don't know what's the reason behind it, my users also complained about that, can someone open my site in Opera to confirm if they are also experiencing it or only me? Screenshot of Opera and Chrome is also attached below. Thanks!
