My Firefox shows all the dates in U.S. format, calendars show Saturday as the first day of the week and decimals are separated by . when they should be separated by ,

I have the browser and my computer OS in Finnish as default and all the settings show, I should have Finnish dates and other settings, but it doesn't help, dates are in U.S. format. How can I change this?

When you last updated or installed, you may have not gotten the correct localization for Firefox, or possibly something broke some settings. You may want to simply re-install Firefox by downloading a Finnish-localized version manually. https://www.mozilla.org/firefox/all/#product-desktop-release

What do you get if you paste this code in the Web Console or Browser Console ?

  • (new Date()).toLocaleString()
  • (new Date()).toLocaleString("fi")

See also this pref on the about:config page.

  • intl.regional_prefs.use_os_locales

Firefoxes WebConsole I got these:

(new Date()).toLocaleString() "3.2.2020 klo 9.09.14" (new Date()).toLocaleString("fi") "3.2.2020 klo 9.09.36"

and the about:config "intl.regional_prefs.use_os_locales" gave "false"
