Thunderbird and Firefox for MAC questions

Hi,

Good to be here. I have just purchased a new iMac and have used MS Windows since the DOS days. I believed it was time I moved over to a MAC but I have the following questions please:

I have used Firefox and Thunderbird for a very long time on Windows and I know these are available on the MAC but, can anyone tell me how I can bring my profiles, settings, address book and bookmarks over to the MAC?

I can backup in Windows using MozBackup but, this is not available on the MAC.

All help/input is very much appreciated.

Many thanks
