How do I re-establish my contacts that you so nicely deleted when you updated the look for them?

My contacts are 90% gone! You had put in a new look for this feature. From the e-mails I have and people have sent me stuff, I have added them to my contacts, however when I address an e-mail to some them that I have added they are not there.

Firefox has no contacts list or email, it is just a web browser.

Is it the change to Gmail that you are referring to? If it is you need to contact Google.
