Translating Moodle: How to find these strings

Moodle translation

I want to translate the strings from the picture. But I can't find them in AMOS. Please help.

Hi Vanyo,

I guess that the text in your picture comes from your browser e.g. Firefox and not from Moodle.

Thank you, Helen,

You are right.
