Does anyone know how to get my phone to translate a French website, to English?

[lucysmam]

My laptop does it automatically & I'm sure I've managed to get my phone to do it before now bur I'm stumped as to how

Do any of you know what magic is involved?

It depends...

Android phone using Chrome, you should find if you go to the web page then click the three dot menu at top right you have Translate as an option.
