Native datepickers fall apart when you need to handle different date formats as user preferences (not as browser default)

The browser, called the User Agent (UA), IS the program the user uses to interact with a website according to his preferences.

That doesn't always work well in practice. I'm bilingual, and my preference is to use the locale closest to the language of the web site I'm visiting because it feels the most culturally coherent and the least surprising.

I just can't reset my regional settings whenever I switch tabs.

How do you configure Firefox to show date-time picker in 24h format?

Maybe. How many users change the defaults, or even know it’s an option?
