For those who are unclear on the differences between the Mozilla package (Netscape is also comparable to Mozilla except they're two different companies) and Firefox / Thunderbird, here it is:

• Mozilla is a complete package meaning it comes with email, browser, address book, newsgroup, and chat applications integrated.
• FireFox is a stand-alone browser application. It doesn't have email built-in. There is a chatzilla extension available.
• Thunderbird is the stand-alone email application. It doesn't have a browser built-in. The address book is included.
• If you use Mozilla for email and click on a link within an email, it will open them in Mozilla not FireFox even when FireFox is the default browser.
• The applications are similar, yet different. The look and feel is different. It requires experiencing it for yourself to understand this.
• Commands and features are not identical. For instance, Mozilla has F9 to open the sidebar with search, history, bookmarks, etc. whereas FireFox only opens Bookmarks and History in the sidepanel via Ctrl+B and Ctrl+H respectively. There are a few extensions to do more with this.
• FireFox has fewer options because it doesn't have other applications integrated with it, which can make it easier to modify.

At this point, Mozilla is tapering off while Mozilla.org moves forward with its brightest star, Firefox.
