Yes, when you install Firefox it should ask you if you want to transfer IE favorites and Netscape's Bookmarks.
I'm not sure about Thunderbird's Address book. Thunderbird is the Firefox version of the email program.
I'm pretty sure you can export Netscape's Address book entries to a file, then import that file to Thunderbird's address book, because I bet they would use the same file name extension, (".ldif" file), but Outlook Express exports it's address book to a .wab file, and I am not sure how you would import that to Thunderbird.

I see lots of recommendations to install and use Firefox 1.0. I currently have IE6 which I use along with Outlook Express 6.0 and Netscape 7.1 and Netscape email which my wife uses.
If I install Firefox, will it transfer favorites from IE or Bookmarks from Netscape? Also, what about email address books in Netscape(wife) and Outlook Express(mine)?
