Beonex Communicator is Mozilla polished for end users. It contains Navigator, Mailnews, Composer, and ChatZilla. Navigator has support for key web standards and a convenient interface. For example, it eases searching the Internet, similar to Apple's Sherlock on Macintosh. The Bookmark Manager can deal with huge collections of bookmarks and allows you to overview and sort them while you are surfing. If you want, you can track the latest headlines or webcams using the Sidebar. The Mailnews client supports multiple IMAP, POP3 and/or news accounts for each user, so you can download and manage all your email from various accounts in one place and store them on your computer or the server. Beonex puts a strong emphasis on security, privacy, and netiquette, to protect the private or confidential information on your computer and to encourage fairness.
The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
Checky is a document validation and analysis extension for Firefox, Mozilla, and Netscape. It provides an easy-to-use interface to many free and commercial online validation and analysis services. It allows the user to validate, analyze, view, and inspect documents containing HTML, XHTML, CSS, RDF, RSS, XML, P3P, hyperlinks, metadata, and many more. It can check Section 508 and WAI compliance of documents with many helpful services. It can help in the design, development, and maintenance of accessible documents for a semantic web.
The Copy URL+ extension for Firefox and Mozilla makes it possible to copy the current document's address to the clipboard along with additional information such as the document's title, the current selection, or both. This behavior could be useful when you want to send an interesting link to a friend by IM or email and out of laziness don't want to copy the parts individually.
The Jumplink extension for Mozilla/Firefox allows you to skip through redirect links and jump directly to the target link. This is especially useful within Hotmail messages, where all links are opened in a frame displaying at the top the useless "Close this window to return to Hotmail". When right-clicking on a link, the Jumplink extension will attempt to determine if it is a redirect link and display menu entries which let you jump through the redirection.
ArchView can open archive files online without downloading the whole archive, just like normal Web pages. It is very fast since it just fetches a small portion of the archive file from the server. It supports RAR and ZIP formats, and HTTP, FTP, and file: protocols. It can present XUL or HTML interface.
