That's the one, Ken.
Laurie may have mentioned Thunderbird?

These products are "just better" than Internet Exploder and Outhouse Express. I'll leave it to other people to give their opinion as to why they think so.
Try it. Install them. If you don't like Firefox or Thunderbird, then you can just carry on with what you have. Nothing ventured, nothing gained.
