For myself I have separate Firefox and Thunderbird profiles in one single folder located in my /home directory and just drag them around from distro to distro.
No - it uses the same profile. I have two separate TB profiles, I run one as normal and one with the -no-remote parameter, and I can use either profile with either TB simply by changing the path to TB. The same applies to FF. Extract and run with the fully qualified path, and it will still use your normal profile.
