Translation of Müllmann

Can you translate: Are you using the firefox browser? Install this tool in your browser window. The ones I suggested the other day are the most useful ones, because we would use it for generic terms which differ from Spanish.
I have not installed ICQ, unfortunately, but I know many people who use other means of communication, perhaps I can down load it! Currently I am unemployed, I have worked as a waitress.
I am 73 and I am learning German because my grandchildren do not speak English. I am learning at the Goethe Institute in London. One last question: why do you want to learn Spanish? Many greetings.
