I've recently downloaded and installed two open source software applications from Mozilla and have to say that, so far, I'm totally impressed and delighted. Firefox is an internet browser with less overhead than Internet Explorer and lots of controls for popups, spyware, password and cookie management, etc. It has more than 100 plugins available to add features one might want and also has a number of "themes" with which to change the look. Installation was a breeze including cleanly importing all settings and favorites from Internet Explorer. Thunderbird is their email application. Looks and feels a lot like Outlook Express .... but again lots better controls and goodies on the side. It did a flawless import of my email settings and archived messages. One of my favorite plugins is the image zoom feature for both Firefox and Thunderbird. A less useful but comforting one called Spoofstick, tells you what website you are truly at the next time you get an email from CitiBank or Paypal wanting you to login and confirm your account information. Thunderbird has a self-learning junk mail feature that allows you to classify your email with a mouse click to help reduce the junk mail that reaches your inbox. Both applications are free and I recommend them.
