    Using Safari causes mbp to overheat and fan run at high speed. Activity monitor under CPU reads Safari 200 plus current web site 200. Yet using Firefox reads FF 200 current site only 20. Can somebody tell me how I might cool things down.

    Have you tried CPU-Manager+? It works like charm for me, and fixed the problems I had with my Mac's CPU & heat (very similar to yours).

    What is it and what does it do? Who wrote the app, do they have a site?

    @Coto - If you want to be helpful, how about giving us a link to the developer site, and not just the app download?

    Acts like malware of some kind. Nothing in that small app that identifies where it even came from, and gatekeeper reported on it when I tried a test launch.
    Don't install it. It added some kind of Launch Agent to my user Library folder, without even asking.
    EtreCheck reported it, so I removed it.
