Open web page with macOS Safari in different language Is it possible to make Safari open a web page in a different language without having to change the whole system language?

I need to test if the Angular translations come out right but changing system language every time is really annoying.
I'm not sure it's possible to independently change Safari’s accept-language, but try this terminal command, replacing ’en-AU’ depending on what language you would like:

/Applications/Safari.app/Contents/MacOS/Safari -AppleLanguages '(en-AU)'


You should be able to do it with Firefox, via Preferences/General/Language
