Another Firefox fan. Firefox has a lot of add-ons. I also use Thunderbird for email. Outlook never works right on my computer. It does okay for a little while then freezes up when retrieving email. Never had a problem with thunderbird, and it has it's own calendar and everything
I have Chrome, but when I used it, it wasn't compatible with some sites. Admittedly it has been quite a while.
