Copy customers infos on a page and paste on aliexpress

Hello, I'm looking for a windows software or a google or firefox extension to copy customers infos on a page, paste these infos on a aliexpress order page (customer shipping address page). Before pasting info on aliexpress your software MUST clear all fields on aliexpress order page, it contains infos from last customer order. Actually we do that by hand (copy manually on our order system / paste manually our customers infos on aliexpress) takes hours... Please suggest us the best solution.
