Firefox doesn't save "contacts" information, as Firefox has no email features of its' own and it has no use for "contacts" data.

About the only place in Firefox where any email address would be saved, is as part of "form fill" data from when you typed that information into a "form" somewhere on the internet in Firefox. If you aren't familiar with SQLite databases and SQLite manager programs, it is almost impossible to find that information in the file where it is stored in Firefox and then be able to read or extract that data.

If you can not import contacts from your Yahoo! contacts/addresses from one of your other email accounts why then indoes it say in "contacts/address's file" under the "Actions" pull down tab "Import Contacts" When I followed instructions & tried to import contacts from my other email address/contacs (564 name & email addresses in csv file format like it says), you automaticly loose your current email addresses you have in your address/contacts file. It does transfer all the names into your current Yahoo! contacts/addresses but not the email addresses
